Greylisting working well

| No TrackBacks

The Gld greylisting utility I'm running with Postfix is working pretty well, and it's already saving me some headaches. I'm still getting other headaches from postmasters that don't quite understand how their mail servers should be configured and some ISPs that just don't care, but that's a different issue. One great thing about greylisting is that it can help BIG if your mail server happens to get hit with a dictionary attack, because of greylisting, all attempts, even to valid email account, will get a temporary bounce, and this is usually enough that the spammer won't bother running through their list again.

I'm going to be looking into cutting back on some of the filtering I'm doing now that greylisting is working, I'll post my updated Postfix config in a week or so with some new notes.
