Exim with exiscan enabled allows you to reject mail considered spam based on the results of an SA scan. The hard part is maintaining a decent blacklist locally if you can't afford the overhead of using online RBL blacklist servers on a heavily used mail server I would imagine.
Another issue with this is what you tell your clients. I recently had a client who I recommended to a certain ISP who received an email from that ISP which was nothing short of scare-mongering. The email was written by the CEO of the ISP, who it appears hadn't a clue about exactly how the software blocked spam or perhaps wasn't that good at articulating in layman's terms exactly how spam was to be blocked. As a result a number of the ISP's clients were instantly worried that anything containing swear words or 'make money' or whatever in the subject would be blocked, which wouldn't be the case (one would hope!). I think a nice alternative is to set a number of different filtering rules on the MTA so that spam that scores very highly (say over 15 on the SA scale) is rejected outright, whereas spam that scores relatively highly on the SA scale has it's subject modified to indicate that the content is possibly spam. Again though this could be seen as unwanted intrusion by some customers... -- Jez http://www.munk.nu/ _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
