[mdlug] Anyone familiar with Qmail. I need some help.

[Jim]

I run a Qmail server using netqmail-1.05. This server has been running 
along fine until
about the last 3 months. Now I find myself in a never ending pit of 
spam. I have firewalled off about 10 different
countries in there entirety. I have throttled NEW email connections to 
about 3 per minute per IP address
via the firewall. I use spamdyke to handle the RBL DNS block lists as 
well as local blocklists.  For some reason
and I am not sure why I am still getting a gazillion bounces.  What is 
weird  is  is that  these  bounces are not
even targeted at my  domain. I call them bounce spam. I have been over 
my qmail configs files till I cannot stand looking
at them. For some reason my system is not rejecting these emails but is 
instead feeding them into the bounce facility.
It's driving me nuts as it pretty much hangs up outgoing mail while 
qmail-remote trys to send out the bounces. Sometimes thousands at a time 
are hung up in the queue not to mention the thousands of double bounces 
that are in my mailbox as well. I can delete the messages in the queue 
but this wipes out legitimate outgoing email as well.
Has anyone seen this problem or have experience with it? I'm baffled.
