I would second the delay greeting -- I've only seen two other issues with Exim:
- if the reverse DNS of the location failed, Exim would log the
failure, and may not send mail altogether (seeing that you are on localhost this should not be an issue -- if that's the header -- if your web server is separate from your mail server, check and make sure reverse DNS will work -- Postfix and spam assassin have this problem as well) 2) your header information is not clear or questionable, and it maybe blacklisting it. I'm not so sure about this one, I remember someone else speaking of it previously, but worth a look.
I'd almost certainly say it's the spammer delay or the reverse DNS (if that's even reasonable) -- but I've never had this issue with a mail client, only desktop clients sending from specific IP's that are questionable. In our setup, we have Exim as a front man on our OS X Tiger server -- it's coupled with spam assassin, postfix, etc, so our setup is not the same as yours.

Are you intentionally delaying the greeting in order to stopspammers? If so, how many seconds are you delaying? I see these sorts of errors from spammers all the time. Try turning debugging on, as it should print out stuff from the smtp connection.

Hi all!
Just installed RoundCube to try it out. So far it looks good, runs fast, and feels smooth.
One problem.
When I send mail, RoundCube says the mail has been sent, but the mail never arrives. An examination of my Exim4 log shows the issue:
2006-03-21 01:27:02 SMTP protocol synchronization error (next input sent too soon: pipelining was advertised): rejected "MIME-Version: 1.0" H=localhost [ 127.0.0.1] next input="Date: Tue, 21 Mar 2006 1:27:02 -0500\r\nFrom: xxxxx <xxxxx@>\r\nTo: xxxxxx@gmail.com\r\nSubject: Test 3\r\nMessage-ID: < fcba0dbf860c58463ee731c15a075a0c@loc"
Exim4 is working fine for sending other mail. I can send mail through it with Mutt for example. It recieves mail fine too.
Anyone seen this problem?
