qmail/qmail-1.03-doublebounce-trim.patch

   1 If you don't want doublebounces to hit your queue a second time
   2 (because you have, say, ten million mailboxes and as much legitimate
   3 email traffic and more spam), the following patch will immediately
   4 discard bouncing bounces.  Note that doublebounceto must start with a
   5 blank line; that is, it must have one newline in it.  A totally empty
   6 file means "use the default of 'posthamster'".

   8 This version was rewritten by Charles Cazabon from my original patch
   9 to include a man page, turn the patch around in the right direction,
  10 and emit its own message for the logfile.
