Sounds OK to me David. I think I'll use something like that as well on my site. On the contact page I could put something like: To ensure that your email is delivered, please put this number on a seperate line at the start of your email: 1590d03f99485bd8fac68320a0e6d605 [EMAIL PROTECTED] Then create a filter file called: md5sum_accept with the above number in it as a regex: "1590d03f99485bd8fac68320a0e6d605" then in .tmda/filters/incoming add the following line at the top of the file, before the reject filters: # acceptable md5sum regex matches for email body field headers-file ~/.tmda/filters/md5sum_accept Then at the end of the incoming filter file configure the reject filters to block any other mail. Could put it on HOLD while testing, maybe with something like: # reject any other mail that gets this far # store temporarily while testing action with 'hold' # or forward to spam collection site # with deliver=mail_addess #to [EMAIL PROTECTED] [EMAIL PROTECTED] to [EMAIL PROTECTED] hold Regards Keith > ----- Original Message ---- > From: Keith Roberts <[EMAIL PROTECTED]> > To: tmda-users@tmda.net > Sent: Saturday, July 7, 2007 8:37:34 AM > Subject: Avalanche of SPAM > > > Hi.
