check_earlytalker: not necessary with Courier, since Courier already does the right thing with its IO buffers. "early talkers" will get tarpitted. nodialup: use zen.spamhaus.org instead. It's more reliable. check_relay: Courier already supports relaying based on a file similar to this plugin, or on authentication. dnsbl: Courier also supports arbitrary DNSBLs. check_spamhelo: no exact analog is available, though Courier can check HELO against SPF. check_basicheaders: no analog, but a trivial pythonfilter or perl plugin. I believe spamassassin does the same checks. check_goodrcptto: not necessary with Courier. clamav: a pythonfilter exists. In my opinion, the best configuration currently available is Courier's smtpd with zen.spamhaus.org RBL, plus pythonfilter with clamav, spamassassin, nosuccessdsn, deliveredto, and if you're into it: greylist. Spamd should be running with Pyzor, Razor2 and DCC. The URICountry module allows you to mark messages from foreign countries with a higher spam confidence level, and is worth considering. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ courier-users mailing list [email protected] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
