So I guess you would want an alpine based solution but it's worth considering putting a tiny OpenBSD spamd box in front of your server. http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man8/spamd.8?query= =3Dspamd http://cvsweb.openbsd.org/cgi-bin/cvsweb/ports/mail/greyscanner/pkg/DESCR?r= ev=3D1.1.1.1&content-type=3Dtext/x-cvsweb-markup You can modify the greyscanner or make your own scripts to do all sorts of checks whilst senders are temporarily delayed by the amount of time that you tell spamd to do so for (time needed to make sure the checks complete basically). I have a script for dnsbl checks such as barracudas list. Valid senders get failure notices too. I love it, the only down side is that mail can be delayed from large providers like gmail or yahoo as happens on the OpenBSD list, though you can use whitelist tables for google network ips.= --- Unsubscribe: alpine-devel+unsubscribe@lists.alpinelinux.org Help: alpine-devel+help@lists.alpinelinux.org ---
