Description Bryan Jacobs 2008-07-21 00:09:46 UTC

I have a mail server which supports GSSAPI for both IMAP and SMTP.  claws-mail does EXACTLY the right thing when IMAP is set to "automatic" auth - it will do GSSAPI if I have kerberos tickets and fall back to LOGIN if I do not.

However, there's no force-GSSAPI option in the "sending" preferences, and I have verified that GSSAPI is not used when I send a message while it's set to automatic.

kmail sends messages using GSSAPI through this server just fine.  This looks like somebody just didn't know GSSAPI was an option for SMTP servers :-).

The server is postfix using dovecot SASL.

It looks like Claws has internal SMTP handling, but uses libetpan for IMAP. 

Looking through src/common/smtp.c shows that SMTP AUTH using GSSAPI is not implemented by Claws.

Yes, this is the reason.

Comment 3 Alexander Gordeev 2010-07-28 16:27:45 UTC

Maybe Claws Mail should use libetpan's SMTP implementation? Are there any objections/difficulties?
