Evolution Mail Source Wizard

Local mail source

\n" \ "

First you need to tell Evolution whether or not you " \ "receive mail locally, and if so, where.

\n" \ "

Your default mail file on this system is " #define local_text_2 \ ".

\n" #define local_text_3_file \ "

That file exists, so you almost certainly want to use it " \ "as a mail source.

\n" #define local_text_3_dir \ "

That directory exists, but you currently have no mail " \ "there. If you aren't sure whether or not you receive mail " \ "on this machine, it's safest to leave it selected.

\n" #define local_text_3_none \ "

However, that directory does not exist.

Remote mail source

Now you need to " \ "configure a remote mail source, if you have one.

To add a remote mail source, choose a protocol from " \ "the list below and click \"Next\".

" #define remote_text_3_must \ "

You have not configured a local mail source, so you " \ "must configure a remote one.
