+1 for Postgrey. My situation was a bit different - running a resource limited server for a handful of domains and spamassassin was clogging up the CPU. Sticking postgrey in front lowered the number of messages SA had to scan and the system was fine for another year or two afterwards. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
