Look at the ispconfig mail logs. /var/log/mail.* logs are probably too long. I had a [email protected] with a weak password. I checked for open relay, deleted the mailbox, deleted the mailq and addeded any attempted logins into my blacklist. Unfortunately I still might have problems. I am waiting for my que to fill up again and then try. http://www.howtoforge.com/forums/showthread.php?t=67719
