Hangs when sending mail via SMTP

Hangs when sending mail via SMTP

[Tassilo Horn]

Hi all,

since 2 or three days (always using the current git master), I have
frequent hangs when sending mail via SMTP.  In *Messages* I get the
usual output:

--8<---------------cut here---------------start------------->8---
235 2.7.0 Authentication successful
250 2.1.0 Ok
250 2.1.5 Ok [4 times]
354 End data with <CR><LF>.<CR><LF>
Sending email 
Sending email done
250 2.0.0 Ok: queued as 28C71D244A
221 2.0.0 Bye
Mark set
Sending...done
--8<---------------cut here---------------end--------------->8---

The hang occurs while "Mark set" is shown in the echo area.  It usually
takes about 20-30 seconds before "Sending...done" appears and the mail
buffer is closed.

What's a bit strange: when I hit C-g during the hang (possibly
repeatedly), I'll get the "Sending...done" immediately without noticing
any bad effect.  The sent mail is also copied to the group I wrote from
as specified by gcc-self setting.

I can also invoke "killall emacs" from the command line which won't kill
emacs but interrupt the hang just as C-g.

Hm, it might not be a Gnus problem, as the latest commits don't look
overly related.  In the same period, I updated my emacs bzr checkout
(TLS issue maybe?) and our university's mail server machine crashed and
was replaced...

Anyway, does anyone have similar issues?

Bye,
Tassilo

Probably the SMTP server sometimes refuses to acknowledge the QUIT
command for some time (smtpmail waits for an answer here).

Yes, that's likely.  It seems to be a server-side issue.  Sometimes it
works immediately, sometimes it hangs.  I'll try to send some test mails
at home this evening, where I can use some other SMTP server.
