From ed3681564ca93350b6c99e393376319a35abefde Mon Sep 17 00:00:00 2001 From: Jeffrey Stedfast Date: Mon, 2 Oct 2000 23:26:53 +0000 Subject: New convenience function to determine if there are any 8bit mime parts in 2000-10-02 Jeffrey Stedfast * camel-mime-message.c (camel_mime_message_has_8bit_parts): New convenience function to determine if there are any 8bit mime parts in a mime message. (camel_mime_message_encode_8bit_parts): New convenience function to recursively reencode all 8bit mime parts to either quoted-printable or base64 depending on which would be the best encoding for that part. * providers/smtp/camel-smtp-transport.c (smtp_data): If the mime message contains 8bit parts and the server doesn't support 8bit transfers, reencode those parts before proceding with the send. (smtp_mail): If the mime message contains 8bit parts and the server supports the 8BITMIME extension to SMTP, notify the server that we'll be sending it 8bit mime parts. (_send_to): Find out if the message contains 8bit parts. svn path=/trunk/; revision=5677 --- camel/providers/smtp/camel-smtp-transport.c | 39 +++++++++++++++++++++-------- 1 file changed, 28 insertions(+), 11 deletions(-) (limited to 'camel/providers') diff --git a/camel/providers/smtp/camel-smtp-transport.c b/camel/providers/smtp/camel-smtp-transport.c index 02a0198f2f..2aae484c88 100644 --- a/camel/providers/smtp/camel-smtp-transport.c +++ b/camel/providers/smtp/camel-smtp-transport.c @@ -70,9 +70,11 @@ static void free_auth_types (CamelService *service, GList *authtypes); static char *get_name (CamelService *service, gboolean brief); static gboolean smtp_helo (CamelSmtpTransport *transport, CamelException *ex); -static gboolean smtp_mail (CamelSmtpTransport *transport, const char *sender, CamelException *ex); +static gboolean smtp_mail (CamelSmtpTransport *transport, const char *sender, + gboolean has_8bit_parts, CamelException *ex); static gboolean smtp_rcpt (CamelSmtpTransport *transport, const char *recipient, CamelException *ex); -static gboolean smtp_data (CamelSmtpTransport *transport, CamelMedium *message, CamelException *ex); +static gboolean smtp_data (CamelSmtpTransport *transport, CamelMedium *message, + gboolean has_8bit_parts, CamelException *ex); static gboolean smtp_rset (CamelSmtpTransport *transport, CamelException *ex); static gboolean smtp_quit (CamelSmtpTransport *transport, CamelException *ex); @@ -350,6 +352,7 @@ _send_to (CamelTransport *transport, CamelMedium *message, CamelInternetAddress *cia; char *recipient, *sender; const char *addr; + gboolean has_8bit_parts; GList *r; sender = g_strdup (camel_mime_message_get_from (CAMEL_MIME_MESSAGE (message))); @@ -371,7 +374,12 @@ _send_to (CamelTransport *transport, CamelMedium *message, return FALSE; } - smtp_mail (smtp_transport, addr, ex); + /* find out if the message has 8bit mime parts */ + has_8bit_parts = camel_mime_message_has_8bit_parts (CAMEL_MIME_MESSAGE (message)); + + /* rfc1652 (8BITMIME) requires that you notify the ESMTP daemon that + you'll be sending an 8bit mime message at "MAIL FROM:" time. */ + smtp_mail (smtp_transport, addr, has_8bit_parts, ex); if (!recipients) { camel_exception_setv (ex, CAMEL_EXCEPTION_SYSTEM, @@ -389,7 +397,10 @@ _send_to (CamelTransport *transport, CamelMedium *message, g_free (recipient); } - if (!smtp_data (smtp_transport, message, ex)) + /* passing in has_8bit_parts saves time as we don't have to + recurse through the message all over again if the user is + not sending 8bit mime parts */ + if (!smtp_data (smtp_transport, message, has_8bit_parts, ex)) return FALSE; /* reset the service for our next transfer session */ @@ -507,13 +518,16 @@ smtp_helo (CamelSmtpTransport *transport, CamelException *ex) } static gboolean -smtp_mail (CamelSmtpTransport *transport, const char *sender, CamelException *ex) +smtp_mail (CamelSmtpTransport *transport, const char *sender, gboolean has_8bit_parts, CamelException *ex) { /* we gotta tell the smtp server who we are.
