[vexim] Dealing with backscatter

[Tim Aslat]

Hi all,

I'm having a wonderful time dealing with approximately 1000 
undeliverable email messages (which I didn't send) an hour for the past 
couple of hours and I'd love to be able to just drop them into a 
blackhole somewhere.

I'm running Vexim ( v2.2.1 ) with some custom patches to allow for 
selective greylisting and a few other bits & bobs.

The problem is, I can't use the vbounce plugin to spamassassin, mainly 
because I have about 50 domains on this particular server, with clients 
sending mail from all over the place, so it's nealry impossible to add 
all possible sender IPs to the whitelist.

Does anyone have a reasonable way to deal with this problem, other than 
shooting all the morons who are accepting mail before rejecting it?

Something quick to set up would be really good.

Cheers

Tim
