hope you can help because googling to death didn't so far. Here's my issue. I get allot of s-p-a-m sent to my server, spamassassin is doing a great job at catching them. But once in a while someone (spam) will try to send to someone that isn't part of my network and then by default exim when it can't find the user ('Unknown User') it automatically sends an error message. But the problem is that it's usually trying to send it back to the spammer, which obviously does not usually resolve and then stays in my 'mailq' for the determined amount of time I have set.
I need to stop this nosense. Can anyone assist me on how to stop exim from sending bounce back emails totally. I do not want to reply to 'unknown user' issues...
Please help??? thanks,
Btw I'm using exim 3.xx
