Are you worried about iptables slowing systems down compared to Postfix (and whatever authentication backend is involved) having to deal with all the unsuccessful login attempts? I don't think that is likely. Also, what is a theoretical performance hit worth to you, when compared to the possible cost of even a single hacked mail account? -Ralph _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
