> Has anyone got SpamAssassin to work with sendmail?? and is it any good??
I had a brief look at spamassassin and vipul's razor, but then decided not to install them. The risk of loosing real mail seemed very high. Plus installing all that perl rubbish looked like a mighty nightmare (no I am not interested in having my system screwed by running some kind of perl-do-it-all-screw-it-all program). In general, it is impossible to block spam reliably. The higher your block rate the higher your risk to loose real stuff. At a *very* rough guess blocking >=80% starts to get dangerous. The best start is to dump black-listed senders. This seems to catch approx 50%. For sendmail, add FEATURE(dnsbl, nputs.orbz.org')dnl FEATURE(dnsbl,elays.orbl.org')dnl FEATURE(dnsbl,elays.ordb.org')dnl FEATURE(dnsbl,elays.osirusoft.com')dnl FEATURE(dnsbl,bs.dorkslayers.com')dnl dnl costs money: dnl FEATURE(dnsbl,ialups.mail-abuse.org')dnl dnl FEATURE(dnsbl,lackholes.mail-abuse.org')dnl dnl FEATURE(dnsbl,elays.mail-abuse.org')dnl at the appropriate place. This will tell RBL's to get stuffed. It might catch @xtra.co.nz and @ihug.co.nz as well, dunno, tell those guys to get a real ISP instead and to stop supporting spammers. Also tell the same to anyone sending from an IP which does not reverse-resolve. This might catch some dial-up users for whom the ISP does not supply reverse-mapping (are there any?). I would very strongly suggest you use spambouncer (www.spambouncer.org) for some months to get an idea what kind of rubbish gets in and how it's filtered, and importantly, how and why those filters fail. Then you can get more adventerous. I can supply some initial setup in case you use procmail already (the spambouncer-supplied one is crap, the author doesn't care fixing that). > I have been looking in to a way of removing spam before i get spam :))) Haven't we all. Cut down your expactations a few notches or you will be disappointed. Volker -- Please do not CC list postings to me.
