Please post (and cc me) if you get a working Perl script. I'm interested in doing this too. You should also look at Bennett Todd's smtpprox; perhaps you can derive an lmtpprox?: http://bent.latency.net/smtpprox/ This is handy for writing filters in Perl that inject headers and accept/deny based on statistics about the message being delivered.
