So called "sender address verification" is supported by some MTAs such as Postfix, and I expect more as this becomes more of a problem, especially since it's trivial to implement. In any event, TMDA provides this ability via the included `smtp-check-sender' script. > Bollux.

These numbers come at a high price though -- my time. TMDA is significantly less time consuming than maintaining content filters. > ...then TMDA is part of the problem.

If I decided to terminate the TMDA project tomorrow, nothing would change. The knowledge is already out there. You might as well just try to make positive contributions to the technology. _____________________________________________ tmda-users mailing list ([EMAIL PROTECTED]) http://tmda.net/lists/listinfo/tmda-users
