pass, protocol tcp, source lan subnet, destination any, port 25, logging checked, gateway default.

Make sure this rule applies before other rules allowing port 25 out like the default lan to any rule. You'll now see green pass icons in your systemlogs at status>systemlogs, firewall tab. If you want to see more than only the last few items set up a remote syslogserver so you can browse through the past few days/weeks or whatever is needed.

You can test with http://www.mxtoolbox.com/. Another idea is probably to add a logging to your smtp pass rule. If one IP appears nearly all of the time you got your offender.
