Ok; we had to be sure there wasn't something listening on 25/tcp yet I can't understand why, as you reported, sometimes ASSP logs an error due to a port being in use... anyways... The fact that the SMTP server sees the emails coming from the 127.0.0.1 IP and the fact that such emails don't carry the ASSP headers seems to indicate that there must be something else running on the system and allowing to reach the SMTP server using the loopback address; such a program has to be listening on a public IP and "tunnelling" the connection toward 127.0.0.1 the public IP listening port may even not be 25; so, the next step may be running nmap against the listening ports and grabbing the "banner" to see if one of those ports returns the SMTP server banner; if that doesn't bring any results, that I'd check if the server is running any kind of web service; in such a case the "assp bypass" may come from some page or cgi allowing to directly send emails ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
