thats also my point of view, but if you're in a business, you can't deal this way. Your Customers NEED to contact you. Many of them are not able to configure DNS the right way. So if you block them, you'll never get their money ;)
Agreed! LOL :) ;-) ... all you need is .. lo aeh money ;-)
good. that can also be done by a script. the problem is that many domain admins aren't agree with you :( Things like: 'your mailsetup is broken, the sender domain exists and has a/mx records.' are the most used respons ;)
Oh yeah, I have enough of mails like this in my archives... I often found myself in the mids of heated debates about the domain name system with some ppl (admins?), although I don't see any argueable parts in it.
maybe they'll learn someday .. never give up hope :)
Perhaps I should change from Aspirine to Prozac.
drugs are not the right way! (but some things looks funnier with it ;)
Spam filtering is not easy, you need really to figure out how many spam and how many legitimate mail youre blocking. if thats ok for you to block 1-5 good ppl and 10-50 bad ppl, do it :)
Well, I got less than 10% noise in my usual mail traffic (see above), but I agree with you, anti-spam isn't kids play, at least not if you want to tune things finely and not just raise some block-all-and-log walls.
right. if you first block all you become and aministration nightmare and angry ppl all around. The important point is to figure out what you need and how you can deal with reality and your needs :)
Junk mail is war. RFCs do not apply.
:) Yep. That's why I act against some RFCs and also block mails with empty sender lines. Which is much fun for recipients of certain, uh, "leisure-oriented" spare-time list mails (Horoscopes, party tips, news flashes, erotica, you know the score...).
MAIL FROM:<> is _NO_ reason for passing anti spam restrictions ;) maybe, in a world where every admin know what he's doing and all ppl would be able to configure there MUA / MTA / DNS etc. correctly we don't have spam anymore :) -- intraDAT AG http://www.intradat.com Wilhelm-Leuschner-Strasse 7 Tel: +49 69-25629-0 D - 60329 Frankfurt am Main Fax: +49 69-25629-256 Junk mail is war.
