Spammers forged my address - help unbury me from bounces?

This sounds like a dictionary attack.  They simply put your domain in and 
run through
hundreds of names and prepend it to your domain.  One or more is bound to 
go through...

Try using the /etc/mail/access file, if you know what IP or domain it is 
coming from...


Then after adding those entries to the access file, run:

makemap hash /etc/mail/access < /etc/mail/access

to rebuild the database.

I worry about my child and the Internet all the time, even though she's
too young to have logged on yet. Here's what I worry about. I worry
that 10 or 15 years from now, she will come to me and say "Daddy, where
were you when they took freedom of the press away from the Internet?"

Unix IS user friendly... It's just selective about who its friends are.
System Administration - It's a dirty job, but somebody said I had to do it.
If you receive something that says 'Send this to everyone you know,
pretend you don't know me.
