Well most of the problems are gone if you don't blindly greylist everyone. Be selective. http://hege.li/howto/spam/etc/postfix/in/whitelist_client.pcre http://hege.li/howto/spam/etc/postfix/in/greylist_client.pcre The first one already handles most of the lists that are mentioned. I hate when mail from my server gets greylisted for absolutely no sane reason. Ofcourse add few generic FCrDNS domains like hotmail.com, yahoo.com, amazon.com.. I see no point playing with IP addresses unless there is no PTR. _______________________________________________ Help us build a comprehensive ClamAV guide: visit http://wiki.clamav.net http://www.clamav.net/support/ml
