The following page has been changed by mperkel: http://wiki.apache.org/spamassassin/OtherTricks ------------------------------------------------------------------------------ Fake MX records can work like greylisting and often much faster. It doesn't require the installation of new software. What you do is add a fake highest and lowest MX record. Normail email will retry but spammers often don't. This is especially true of virus infected windows zombie spam. Here's an example MX configuration. {{{ fake0.domain.com 10 - realmx.domain.com 20 + realmx.domain.com 20 fake1.domain.com 30 }}} The fake records can either be undefined or can point to dead IP addresses or to real IP addresses with port 25 closed. On the lowest numbered MX be sure it's pointed to a closed port because if you just use a temporary error then Qmail, which is not RFC compatible, will never move up to the next MX record.
