This seems to work but is there anyway to insure that it does not block any
bounces generated internally by Exim itself? I see where it has blocked the
fake bounces as its supposed to but I also see this entry and not sure what
it means:
2005-12-05 20:39:30 H=localhost (
www.mydomain.com) [127.0.0.1] F=<> rejected
RCPT <smith@???>: no bounces from clients
Not sure where this came from. Could be webmail but no idea. Its the only
log entry out of place, the many, many others blocked seem to all be fake
bounces. Perhaps its nothing.
Also, I have several thousand messages in my mail input queue. I am sure
MANY are these faked bounces. Any idea how to clean those out without
waiting a week?
