Mail Server or Domain banned?

How can I find out if my mail server has been banned or if the administrator
banned my domain name?

Not enough info to go on. Are you running your own mail server? What makes
you think it's been blacklisted? Are you getting bounce messages/NDRs?

No, we are talking POP mail. I'm afraid a system administrator might be
sabotaging me.

Any email sent from mydomain.com is rejected by saiddomain.com. I think the
system administrator blocked mydomain.com from saiddomain.com.

In order to determine if this is true, I need to make sure that
mydomain.com's ISP server hasn't been blacklisted by saiddomain.com's ISP
server.

How would I determine that?

The ability to check to see if the administrator of domain A has blocked
mail from domain B exists only if the administrator of A publishes the
information. However, you might be able to get a clue whether this has
happened or not if you try a manual SMTP session from domain B to A:
telnet smtp.domaina.com 25 <-you type this

220 smtp.comaina.com ready at Fri, 06 Aug 2004 <- other answers
helo me.domainb.com <- you type this
....some response here...

At this point, if the response is a rejection message, you know.
