Are you intentionally delaying the greeting in order to stop
spammers? 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?
