grep the Postfix logs, get a single incident of this and show everything. Then use the time and date stamping to find the same exact transaction from the IMail end. Look at both sets of logs and see what they say. > -------------------------------------------------------------------------- -------------- > > To: [EMAIL PROTECTED] (Postmaster) Subject: Postfix SMTP server: > errors from unknown[12.159.188.6] > Transcript of session follows. > Out: 220 imgw-2.ly.net - ESMTP - Postfix - Attn: UCE trespassers will be > pursued. > In: > Out: 500 Error: bad syntax > In: quit > Out: 221 Bye Bad syntax in a session transcript can be several things. The session transcript means nothing other than, "Hi, you have a problem." In contrast, the logs should say what the problem is. If using Postfix on FreeBSD set up basically as Len suggests, grep 12.159.188.6 /var/log/maillog That should get you some specific incidents, and perhaps the answer. Take the results and use them as a basis for more gepping, and/or for looking into your IMail logs. As long as you keep looking at session transcripts you will not have enough information. --Eric
