OpenBSD uses a specific daemon: https://man.openbsd.org/spamd to perform blacklisting, greylisting, tarpitting etc. (Don't confuse this with SpamAssassin's "spamd". They're completely different.) I gather that spamd used in conjunction with pf (their packet filter) and a real mail daemon can be effective. I've never had to use such a setup myself. -- Dennis Davis <[email protected]> -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
