SMTP protocol violation, does not wait for SMTP server to respond, hence behaves like a spammer

Description of problem:
When trying to send an email with evolution to an SMTP server that
enforces RFCs mail is rejected.
Evolution does not wait for the SMTP conversation and tries to jump
the process, just chucking all data at the SMTP server without waiting
for the normal procedure described in the RFC resulting in the
following error from the SMTP server:
2004-09-03 21:09:42 SMTP protocol violation: synchronization error
(input sent without waiting for greeting): rejected connection from
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.configure evolution to use an SMTP server that enforces the correct
2.click send and receive to get the error from Evolution: Welcome
response error: Connection reset by peer.
Actual Results: The mail is rejected with errors on both sides
Expected Results: Evolution should negotiate the wait for the SMTP
The SMTP server used was exim 4.42
relay.harkness.co.uk, which has IP addresses 18.104.22.168 and
I will happily provide logs of access attempts too.

Xander are you still seeing this?
For what it's worth, I run Exim 4.5 at home and can send mails from Evolution
2.7 to the server just fine. Perhaps this has been fixed since Evolution 1.5.
I'll see if I can research this upstream. Xander, do recall any upstream bugs
related to this?
I was only able to find one bug related to this upstream, but it turned out to
be a false alarm. The fault was placed on TLS, not Evolution.
I can not confirm this behavior in current Rawhide packages, nor can I confirm
that this was ever actually a bug in Evolution. Since this bug report is
approaching its 2nd birthday, I'm going to close this as NOTABUG and wait for
someone to report the problem again.
