I recently set up a qmail server and am very much a newbie to qmail as
well as running a mail server in general. I'm trying to get a handle
on what is happening and why. Here is what I've been seeing, I got
everything (qmail-smtp (open), qmail-send, qmail-popd (blocked))
working the started to get mysterious messages something to the effect
of:

MQ> Message follows:


Then I started getting a lot of the messages referenced in here. MS
patch etc. My first concern was that I had an open relay, that
spammer where using, and hence the reason for the above message
showing up on my doorstep. I looked into it and it doesn't appear
that it is an open relay, rcphosts includes my host and my laptops
IP. (Although wouldn't it be possible to spoof this I'll leave that
for another thread).

My conclusion is that my email address was picked up and is now being
used as a reply to for the spam. Likewise I'm recieving the spam as
well. Is this close to correct? I appreciate any help or wisdom in
this. Is this normal when a M$ worm/virus surfaces. I don't run M$
anywhere.


Thanks in advance
