I use Postfix 2.2.10 and I wonder what common practice is to stop backscatter email? I see that body checks and header checks are recommended.
I turned off grey listing and have since been looking to improve my spam prevention without it. So far, I have studied the sorbs black lists and I've added a few more. I was originally using just dnsbl.sorbs.net where I have added the spam list and all the rhsbl lists. I am also using just bl.spamcop.net and I have been trying to produce my own dns black list. I figure if I add more black lists I will stop more spam from getting onto my mail servers in the first place. The trick is figuring out which ones to add. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
