The only solution I've come up with to this problem is to reject blocked addresses *before* you close the connecting with the sending mailserver, and the only MTA that can do this nicely that I've found is courier with the localmailfilter feature. (see my earlier message to this list on courier, spamassasin, and maildrop integration for details) Now, what are people's thoughs on this list about the 'Senders Permitted From' txt DNS records to prefvent forgeing 'From' addresses? http://spf.pobox.com/ -- -------------------------------------------------------------------------- Troy Benjegerdes 'da hozer' [EMAIL PROTECTED] Somone asked my why I work on this free (http://www.fsf.org/philosophy/) software stuff and not get a real job.
