Hi, here i would suggest using Greylisting policy for all incoming mail. Here's the explanation of how it works: http://projects.puremagic.com/greylisting/
And here's Postgrey, Greylisting policy server for Postfix: http://postgrey.schweikert.ch/ It really prevents most of the (I mean more than 95% maybe) spam. Currently I don't have any anti-spam solution on my servers except postgrey. regards, Kerem HADIMLI On 9/27/07, Vladimir Likhachev <[EMAIL PROTECTED]> wrote: > > > > > > > ________________________________ > > > From: [EMAIL PROTECTED] > > To: [email protected] > > Subject: Re: [Dbmail] Spammer and dbmail > > Date: Wed, 26 Sep 2007 13:02:48 +0200 > > > > On Mittwoch, 26.
