But - have you tried connecting to the SMTP port via Telnet to verify what is happening manually?
Subject: Re:SMTP Authentication Problem
Interestingly enough - today while searching for SSL errors I get from Citadel - I found the following link:
Where other people are complaining about the same issue - but also... where people are having trouble with sending/receiving mail.
And the suggestion made by the people trying to help involved connecting to Port 25 via Telnet to see what was happening.
I don't think my error, which is in this guy's logs...
"SSL_accept failed: errval=5, retval=-1 (Input/output error)"
Is related to send errors using SMTP - but it is interesting that it isn't just me getting this error in my logs.
Anyhow - maybe the link above will assist you.
