Log outgoing SMTP traffic on a PIX 506e

Unanswered Question
Dec 15th, 2008

I have a Cisco PIX 506e which I would like to log all outbound SMTP traffic down to internal IP address. I have a rogue spammer on my network which I would like to track down. I am not to familar with the CLI and prefer to work with the PDM if possible. I setup a Syslog server, but it seems to be capturing almost too much data and I dont see any SMTP traffic other than from my mail server. Here is my current config

I have this problem too.

=========

if this is your setup then, you will only see packets from your mail server on port 25 in the PIX fw logs, which is not that helpful.

To track down the spammer in your network, you will have to check the logs from your MAIL/SMTP server.

You can also try opensource SPAM filters like spamassassin

Well I am thinking someone on my network has a trojan which is spamming. The clients sit on the same LAN as my mail server
