<title> A Guide to the Evolution Mailer</title>
<para>
<application>Evolution</application> email is like other email
programs in all the ways you would hope:
<itemizedlist>
<listitem>
<para>
It can sort and organize your mail in a wide variety of ways with
folders, searches, and filters.
</para>
</listitem>
<listitem>
<para>
It can send and receive mail in HTML or as plain text, and
permits multiple file attachments.
</para>
</listitem>
<listitem>
<para>
It supports multiple mail sources, including <glossterm
linkend="imap">IMAP</glossterm>, <glossterm
linkend="pop">POP3</glossterm>, local
<systemitem><filename>mbox</filename></systemitem> and
<systemitem><filename>mh</filename></systemitem> files, and
even NNTP messages (newsgroups), which aren't technically
email.
</para>
</listitem>
</itemizedlist>
</para>
<para>
However, <application>Evolution</application> has some important
differences. First, it's built to handle very large amounts of
mail without slowing down or crashing. Both the <link
linkend="usage-mail-organize-filters">filtering</link> and <link
linkend="usage-mail-organize-search">searching</link> functions
were built for speed and efficiency on gargantuan volumes of
mail. There's also the <application>Evolution</application>
<link linkend="usage-mail-organize-vFolders">Virtual
Folder</link>, an advanced organizational feature not found in
many other mail clients. If you get a lot of mail, or if you keep
every message you get in case you need to refer to it later,
you'll find this feature especially useful.

<title>Reading, Getting and Sending Mail</title>
<sect2 id="usage-mail-getnsend-read">
<title>Reading Mail</title>
<para>
You can start reading email by clicking
<guibutton>Inbox</guibutton> in the shortcut bar. The first
time you use <application>Evolution</application>, it will
start with the <interface>Inbox</interface> open and show you a
message from Ximian welcoming you to the application.
</para>
<para>
Your <application>Evolution</application>
<guilabel>Inbox</guilabel> will look something like the one in
<xref linkend="usage-mail-intro-fig">.
If you find the <interface>view pane</interface> too small, you can resize
the pane, enlarge the whole window, or double-click on the
message in the <interface>message list</interface> to have it
open in a new window. To change the sizes of a pane, just click
and hold on the divider between the two panes. Then you can drag
up and down to select the size of the panes. Just like with
folders, you can right-click on messages in the message list and
get a menu of possible actions.

This is where your email is displayed.

<para>
<inlinegraphic fileref="fig/full-2.png"></inlinegraphic>
<guilabel>Email List</guilabel>
</para>
<para>
The <guilabel>Email List</guilabel> lists off all the emails that you
have. This includes all your read, unread, and email that is flagged to
be deleted.
</para>
<para>
Most of the mail-related actions you'll want to perform are
listed in the <guimenu>Message</guimenu> menu in the menu
bar. The most frequently used ones, like
<guimenuitem>Reply</guimenuitem> and
<guimenuitem>Forward</guimenuitem>, also appear as buttons in
the toolbar, and almost all of them are duplicated in the
right-click menu and as keyboard shortcuts, which tend to be
faster once you get the hang of them. You can choose
whichever way you like best; the idea is that the software
should work the way you want, rather than making you work the
way the it does.
<tip id="view-headers">
<title>Take a look at the headers</title>
<para>
To look at the entire source of your email message, including
all the header information, select
<menuchoice><guimenu>View</guimenu><guimenuitem>Source</guimenuitem></menuchoice>
</para>
</tip>
</para>
<sect3 id="usage-mail-listorder">
<title>Sorting the message list</title>
<para>
One of the ways <application>Evolution</application> lets
you choose the way you work is the way it lets you sort your
message lists. To sort by sender, subject, or date, click
on the bars with those labels at the top of the message
list. The direction of the arrow next to the label indicates
the direction of the sort, and if you click again, you'll
sort them in reverse order. For example, click once on
<guilabel>Date</guilabel> to sort messages by date from
oldest to newest. Click again, and
<application>Evolution</application> sorts the list from
newest to oldest. You can also right-click on the message
header bars to get a set of sorting options, and add or
remove columns from the message list. You can find detailed
instructions on how to customize your message display
columns in <xref linkend="usage-mail-organize-columns">.
</para>
<para>
You can also choose a threaded message view. Select
<menuchoice> <guimenu>View</guimenu>
<guimenuitem>Threaded</guimenuitem> </menuchoice> to turn
the threaded view on or off. When you select this option,
<application>Evolution</application> groups the replies to a
message with the original, so you can follow the thread of a
conversation from one message to the next.
</para>
</sect3>
<sect3 id="usage-mail-getnsend-delete">
<title>Deleting Mail</title>
<para>
Once you've read your mail, you may want to get rid of
it. To mark a message for deletion, select it in the the
<interface>message list</interface> by clicking on it once.
Then click on the <guibutton>Delete</guibutton> button in
the tool bar. Or, right-click on a message and choose
<guimenuitem>Delete</guimenuitem> from the right-click
menu. The message will appear with a line through it, to
show that you've marked it for deletion.
</para>
<para>
If you change your mind and decide you want to keep it,
select <menuchoice> <guimenu>Message</guimenu>
<guimenuitem>Undelete</guimenuitem></menuchoice>. If you
really want to get rid of it, choose
<guimenuitem>Expunge</guimenuitem> from the
<guimenu>Folder</guimenu> menu. That will delete it
permanently.
</para>
</sect3>
</sect2>
<sect2 id="usage-mail-getnsend-get">
<title>Checking Mail</title>
<para>
Now that you've had a look around the
<interface>Inbox</interface>, it's time to check for new mail.
Click <guibutton>Get mail</guibutton> in the toolbar to check
your mail. If it's the first time you've done so, the
<interface>mail setup assistant</interface> will ask you for
the information it needs to check your mail (see <xref
linkend="config-setupassist"> for more information).
</para>
<para>
Then, you need to enter your email
password. <application>Evolution</application> will remember
your password until until you select <menuchoice>
<guimenu>Settings</guimenu> <guimenuitem>Forget
Passwords</guimenuitem> </menuchoice>.
</para>
<para>
Once it's validated the password,
<application>Evolution</application> will check your mail.
New mail will appear in the local <interface>Inbox</interface>
if you're using a <glossterm>POP</glossterm> account, and in
your <glossterm>IMAP</glossterm> folders if you use IMAP. If
you have chosen to use IMAP, and you have multiple folders on
your IMAP server, you may need to subscribe to them. To learn
how to use the subscription manager, read <xref
linkend="usage-mail-subscriptions">.
</para>
<note id="badmailsettings">
<title>Can't Check Mail?</title>
<para>
If you get an error message instead of mail, you probably need
to change your network settings. To learn how to do that,
have a look at <xref linkend="config-prefs-mail-network">, or
ask your system administrator.
</para>
</note>
<sect3 id="usage-mail-getnsend-get-news">
<title>Using Evolution for News </title>
<para>
Newsgroups are so similar to email that there's no reason not
to read them side by side. If you want to do that, add a
news source to your configuration (see <xref
linkend="config-prefs-network-news">). The news server will
appear as a remote server, and will look quite similar to an
IMAP folder. When you click <guibutton>Get Mail</guibutton>,
<application>Evolution</application> will also check for news
messages.
</para>
</sect3>
<sect3 id="usage-mail-getnsend-get-attach">
<title>Attachments and HTML Mail</title>
<para>
If someone sends you an <glossterm>attachment</glossterm>, a
file attached to an email,
<application>Evolution</application> will display the file
at the bottom of the message to which it's attached. Text,
HTML, and most images will be displayed within the message
itself. For other files,
<application>Evolution</application> will show an icon at
the end of the message. Right-click on the icon to get a
list of options which will vary depending on the type of
attachment. You will have the option to display most files
as part of the message, export them to a different
application (images to Eye of GNOME, spreadsheets to
Gnumeric, and so forth), or save them to disk.
</para>
<para>
<application>Evolution</application> can also display
HTML-formatted mail, complete with graphics. HTML
formatting will display automatically, although you can
turn it off if you prefer.
</para>

<sect2 id="usage-mail-getnsend-send">
<title>Writing and Sending Mail</title>

You can start writing a new email message by selecting
<menuchoice> <guimenu>File</guimenu>
<guisubmenu>New</guisubmenu> <guimenuitem>
Mail Message</guimenuitem></menuchoice>, or by pressing the
<guibutton>Compose</guibutton> button in the Inbox toolbar.
When you do so, the <interface>New Message</interface> window

<sect3 id="usage-mail-getnsend-send-delay">
<title>Saving Messages for Later</title>
<para>
Evolution will send mail immediately unless you tell it to
do otherwise by selecting <menuchoice>
<guimenu>File</guimenu> <guimenuitem>Send
Later</guimenuitem></menuchoice>. This will add your
messages to the <guilabel>Outbox</guilabel> queue. Then,
when you press <guibutton>Send</guibutton> in another
message, or <guibutton>Get Mail</guibutton> in the main
mail window, all your unsent messages will go out at once.
Many times, one might want to use "Send Later" becuase it gives
you a chance to change your mind about a message before it
is sent. This way, you may not say something you may regret.
</para>
<para>
To learn more about how you can specify message queue and
filter behavior, see <xref linkend="config-prefs-mail">.
</para>
<para>
You can also choose to save messages as drafts or as text
files. Choose
<menuchoice>
<guimenu>File</guimenu>
<guimenuitem>Save</guimenuitem>
</menuchoice>
or <guimenuitem>Save As</guimenuitem> to save your message
as a text file. If you prefer to keep your message in a
folder (the <guilabel>Drafts</guilabel> folder would be the
obvious place), you can select <menuchoice>

You can probably guess the purpose of the buttons labelled
<guibutton>Cut</guibutton>, <guibutton>Copy</guibutton>,
<guibutton>Paste</guibutton>, <guibutton>Undo</guibutton>
and <guibutton>Redo</guibutton>, but there's a bit more to

you'll see how <application>Evolution</application> handles
additional features, including large recipient lists,

<sect4 id="usage-mail-getnsend-send-attach">
<title>Attachments</title>
<para>
If you want to attach a file to your email message, you
can drag it from your desktop into the message window, or
click the button in the toolbar with a paper clip on it,
labelled <guibutton>Attach</guibutton>. If you click the
<guibutton>Attach</guibutton> button,
<application>Evolution</application> will open a file
selection dialog box to ask you which file you want to
send. Select the file and click <guilabel>OK</guilabel>.

<para>
To hide the display of files you've attached to the

When you send the message, a copy of the attached file
will go with it. Be aware that big attachments can take a
long time to download.
</para>
<para>
When recieving a message that has an attached image,
<application>Evolution</application> gives you the choice
whether to view it or not. You can choose to have it
always shown, load images only if the sender is in your
addressbook, or never load images.
</para>
</sect4>
<sect4 id="usage-mail-getnsend-send-to-types">
<title>Types of Recipients</title>
<para>
<application>Evolution</application>, like most email
programs recognizes three types of addressee: primary
recipients, secondary recipients, and hidden ("blind")
recipients.
</para>
<para>
The simplest way to direct a message is to put the email
address or addresses in the <guilabel>To:</guilabel>
field, which denotes primary recipients. To send mail to
more than one or two people, you can use the the
<guilabel>Cc:</guilabel> field.
</para>
<para>
Hearkening back to the dark ages when people used
typewriters and there were no copy machines, "Cc" stands
for "Carbon Copy." Use it whenever you want to share a
message you've written to someone else.
<example id="ex-mail-cc">
<title>Using the Cc: field</title>
<para>
When Susan sends an email to a client, she puts her
co-worker, Tim, in the in the
<guilabel>Cc:</guilabel> field, so that he know
what's going on. The client can see that Tim also
received the message, and knows that he can talk to
Tim about the message as well.
</para>
</example>
</para>
<para>
<example id="ex-mail-bcc">
<title>Using the Bcc: field</title>
<para>
Tim is sending an email announcement to all of his
company's clients, some of whom are in competition
with each other, and all of whom value their
privacy. He needs to use the
<guilabel>Bcc:</guilabel> field here. If he puts
every address from his address book's "Clients"
category into the <guilabel>To:</guilabel> or
<guilabel>Cc:</guilabel> fields, he'll make the
company's <emphasis>entire</emphasis> client list
public. However, but putting his "Clients" addressbook
into the Bcc: section, that will cause them to be hidden
from the competition. It seems insignificant, but it can
make a huge difference in some situations.

or choose <guimenuitem>Reply to Sender</guimenuitem> from
the message's right-click menu. That will open the
<interface>message composer</interface>. The
<guilabel>To:</guilabel> and <guilabel>Subject</guilabel>
fields will already be filled, although you can alter them
if you wish. In addition, the full text of the old message
is inserted into the new message, either in italics (for
HTML display) or with the > character before each line
(in plain text mode), to indicate that it's part of the
previous message. People often intersperse their message
with the quoted material as shown in <xref

If you're reading a message with several recipients, you may

of people in the <guilabel>Cc:</guilabel> or
<guilabel>To:</guilabel> fields, this can save substantial
amounts of time.
<example>
<title>Using the Reply to All feature</title>
<para>
Susan sends an email to a client and sends copies to Tim
and to an internal company mailing list of co-workers.
If Tim wants to make a comment for all of them to read,
he uses <guibutton>Reply to All</guibutton>, but if he
just wants to tell Susan that he agrees with her, he
uses <guibutton>Reply</guibutton>. Note that his reply
will not reach anyone that Susan put on her
<guilabel>Bcc</guilabel> list, since that list is not
shared with anyone.
</para>
</example>
</para>
<para>
You may want to reply to a whole mailing list. For this, you would
use the <guibutton>Reply to List</guibutton> instead of the standard
<guibutton>Reply</guibutton> or <guibutton>Reply to All</guibutton>.
<note>
<title>Whats a Mailing List?</title>
<para>
Mailing Lists are one of the most popular ways in which group
collaboration on the internet works. They allow people to send one
message to one server. The server then knows who is subscribed to the
mailing list, and sends a copy of your email to all the people on the
list. As a matter of fact, mailing lists are one of the main ways in
which <application>Evolution</application> was developed.
</para>
<para>
There are two different types of mailing lists. The first is a
general submission list. That means that anyone can write to the
list. The second is a managed list. The managed lists have
someone running them. They can do as little as limit who
subscribes to the list or as much as moderate which emails get on
the list.

prefer not to receive HTML-enhanced mail because it is
slower to download and display. <emphasis>Some</emphasis>
people refer to HTML mail as "the root of all evil" and
get very angry if you send them HTML mail, which is why

<para>
HTML formatting tools are located in the toolbar just above
the space where you'll actually compose the message, and

you hold your mouse over the buttons. The buttons fall
into four categories:
<variablelist>
<varlistentry>
<term>Headers and lists</term>
<listitem>
<para>
At the left edge of the toolbar, you can choose
<guilabel>Normal</guilabel> for a default text style
or <guilabel>Header 1</guilabel> through
<guilabel>Header 6</guilabel> for varying sizes of
header from large (1) to tiny (6). Other styles
include <guilabel>pre</guilabel>, to use the HTML

</para>
</listitem>
</varlistentry>
<varlistentry>
<term>Text style</term>
<listitem>
<para>
Use these buttons to determine the way your letters

The post office forwards your mail for you when you change

mistake. The email <guilabel>Forward</guilabel> button
works in much the same way. It's particularly useful if you
have received a message and you think someone else would
like to see it. You can forward a message as an attachment
to a new message (this is the default) or
you can send it <glossterm linkend="inline">inline</glossterm> as a quoted
portion of the message you are sending. Attachment
forwarding is best if you want to send the full, unaltered
message on to someone else. Inline forwarding is best if
you want to send portions of a message, or if you have a
large number of comments on different sections of the
message you are forwarding. Remember to note from whom the
message came, and where, if at all, you have removed or
altered content.

<title>Staying organized: Mail Filters in Evolution</title>
<para>
Filters work very much like the mail room in a large company.
Their purpose is to bundle, sort, and distribute mail to the
various folders.
In addition, you can have multiple filters performing multiple
actions that may effect the same message in several ways. For
example, your filters could put copies of one message into
multiple folders, or keep a copy and send one to another
person as well, and it can do that in under a second. Which is
to say, it's faster and more flexible than an actual person
with a pile of envelopes.
</para>
<para>
Most often, you'll want to have
<application>Evolution</application> put mail into different
folders, but you can have it do almost anything you like.
People who get lots of mail, or who often need to refer to old
messages, find filters especially helpful, but they can greatly benefit
anybody who gets more than a few messages a day. To
create a filter, open the <interface>filter

<title>Getting Really Organized with Virtual Folders</title>
<para>
If filters aren't flexible enough for you, or you find
yourself performing the same search again and again, consider
a virtual folder. Virtual folders, or vFolders, are an
advanced way of viewing your email messages within
<application>Evolution</application>. If you get a lot of
mail or often forget where you put messages, virtual folders can help
you stay on top of things.
</para>
<para>
A virtual folder is really a hybrid of all the other organizational
tools: it looks like a folder, it acts like a search, and you
set it up like a filter. In other words, while a conventional
folder actually contains messages, a virtual folder is a view of
messages that may be in several different folders. The
messages it contains are determined on the fly using a set of
criteria you choose in advance.
</para>
<para>
As messages that meet the virtual folder criteria arrive or are
deleted, <application>Evolution</application> will
automatically place them in and remove them from the
virtual folder contents list. When you delete a message, it gets
erased from the folder in which it actually exists, as well as
any virtual folders which display it.
</para>
<para>
Imagine a business trying to keep track of mail from hundreds
of vendors and clients, or a university with overlapping and
changing groups of faculty, staff, administrators and
students. The more mail you need to organize, the less you
can afford the sort of confusion that stems from an
organizational system that's not flexible enough. Virtual folders
make for better organization because they can accept
overlapping groups in a way that regular folders and filing
systems can't.
</para>
<example id="usage-mail-organize-vFolders-ex">
<title>Using Folders, Searches, and Virtual Folders</title>
<para>
To organize my mail box, I set up a virtual folder for
emails from my friend and co-worker Anna. I have another
one for messages that have "ximian.com" in the address and
"Evolution" in the subject line, so I can keep a record of
what people from work send me about
<application>Evolution</application>. If Anna sends me a
message about anything other than Evolution, it only shows
up in the "Anna" folder. When Anna sends me mail about the
user interface for <application>Evolution</application>, I
can see that message both in the "Anna" virtual folder and
in the "Internal Evolution Discussion" virtual folder.

To create a virtual folder, select <menuchoice>
<guimenu>Settings</guimenu> <guimenuitem>Virtual Folder

linkend="usage-mail-organize-filters">), and which
presents you with a list of virtual folders you have previously
created. If you have created any virtual folders, they are listed
here, and you can select, edit or remove them if you wish.
If you have not created any, there will be only one available
option: click <guibutton>Add</guibutton> to add a new
Virtual Folder.
</para>
<para>
You can enter a name for your virtual folder in the
<guilabel>Name</guilabel>. Then, tell
<application>Evolution</application> what messages to look
for. This process is exactly like filter creation: decide
between <guilabel>Match all parts</guilabel> and
<guilabel>Match any part</guilabel>, then choose what part of
the message to look in, what sort of matching to perform, and
specify exactly what it is that you want to find, be it a
line of text, a score, a regular expression, or a particular date or
range of dates.

If you have configured any IMAP (mail) or NNTP (news)
servers, you will see them listed in the left half of the
subscription management window. Click on a server to select
it, and you will see the folders or newsgroups available to
you. You can then select individual folders and subscribe to
them, or remove yourself from the subscription list.

<title>What is Encryption?</title>
<para>
Encryption is an ancient method of changing readable text to unreadable
text that dates back to Egyptian times. Encryption takes the statement
"Evolution" and turns it into something which cannot be read without help
through decryption.
<example>
<title>Encryption Example</title>
<para>
Kevin orders an <application>Evolution</application> t-shirt from
Ximian, Inc. over the internet. He puts in his credit card number
which is 1234-567-8901. For security, his computer encrypts the
credit card number so it can be safely transmitted over the internet.
The number now is @#$23ui7yr87#@!48970fsd, which holds no intentional
resemblance to the inital number. When the information gets to
Ximian, Inc. it'll be decrypted into the inital number.
</para>
</example>
Encryption can be used in email in two ways: to verify that the sender is
the real sender, and to hide the message while in transmission.
<application>Evolution</application> has the capability to do both.

<title>Generating your PGP key</title>
<para>
First, you need to create a PGP key. To do this, you'll need GPG
installed.
</para>
<tip>
<title>GPG Versions</title>
<para>
This manual covers version 1.0.6 of GPG. If your version is different,
this may not be entirely accurate. You may find out your version number
by typing in: <command>gpg --version</command>.
</para>
</tip>
<para>
You can start by typing in: <command>gpg --gen-key</command>. At the
first question, select 1. The next question asks you about key length.
The longer the key, more stronger it is. However, the longer the key, the
longer it takes to generate. This is your choice. However, 1024 bits
(default) should be adequate. The next question asks you if you want your
key to expire. Expiring keys make your key invalid after a certain amount
of time, so old keys don't float around active. This is the same concept
as a coupon at a supermarket. Next, you'll type in your Real name, your
email address, and a comment. You should not forge this information, as
it is used later to verify who you are. Assuming that all your
information is correct, press "O" to continue. GPG now asks you for a
passphrase. This is a password which you will need to decrypt and encrypt
messages. This can be any length, with any characters in it. It is case
sensitive, which means that it does know the difference between capital
letters and lower-case. Now your key is generated. It is recommend you
surf the internet, read your email, or write a letter in a word
processor. This help creates randomness in the key.
</para>
<para>
Once this is completed, you'll be dropped back to the command line.
Now you can view your key information by typing <command>gpg
--list-keys</command>. You should see something similar to this:

You'll now need to upload your public key to a keyserver, so that your
friends can use your key. You'll need to know the ID of your key, which
is after the 1024D on the line beginning with pub. For this example, it
is 32j38dk2. You now type in <command>gpg --send-keys --keyserver
wwwkeys.pgp.net 32j38dk2</command>. Substitute your key ID for 32j38dk2.
You will be prompted to type in your password <!-- verify that you need to
enter your password here --> and your key will be uploaded for your
friends to download.

You can either sign or encrypt a message. When you sign a message, verify

prying eyes to view it while it's in tranmission.
