I doubt that would be very effective. Much of the Russian backscatter hitting my mailbox is of spam with forged Received: lines pointing to my outbound mail system including IP addresses reverse DNS names. The forgeries have no obvious defects except for certain external evidence showing that they are forgeries. I've been told that attention paid to me is not unique. > If you really want to get rid of bad bounces, try BATV, > http://www.mipassoc.org/batv/index.html, which puts a signature in the > bounce address that all your real bounces will then have.

For now it might be sufficient to do something like; - set sendmail.cf to add an oddball X- header that you change occassionally - set sendmail.cf to use procmail as the "local mailer" as described in cf/README - use two levels of procmail recipes first to detect NDRs and then to reject all that lack your current or most recent X-headers Vernon Schryver [EMAIL PROTECTED] _______________________________________________ DCC mailing list [email protected] http://www.rhyolite.com/mailman/listinfo/dcc
