if you can deal with it trying once then deleting double bounce, you can apply
this patch. It has worked fantastically for me.:) I am using netqmail and I
applied the patch manually because I had previously patched qmail-send for a
custom function, it was so small. It does not patch qmail scanner, but
qmail-send.
I am supplying it here because I do not remember where I got it :(
---------------------- info for patch and patch starts here --------------
If you don't want doublebounces to hit your queue a second time
(because you have, say, ten million mailboxes and as much legitimate
email traffic and more spam), the following patch will immediately
discard bouncing bounces. Note that doublebounceto must start with a
blank line; that is, it must have one newline in it. A totally empty
file means "use the default of 'posthamster'".
This version was rewritten by Charles Cazabon from my original patch
to include a man page, turn the patch around in the right direction,
and emit its own message for the logfile.
Apply this patch as so:
cd /usr/local/src/qmail-1.03
patch <doublebounce-trim.patch
