email sabotage?

[Rob]

We are talking POP mail here. 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 has 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? Or any help in determining what's going on here
would be appreciated.

If they are blocking "open relay" or SPAM domains,
chances are they are getting that information from a
company that provides a database of Open Relays/SPAM
servers.

Look up your hostname on a http://www.ordb.com or
http://www.spamhaus.org

If your domain is listed in on of those, you'd want to
take whatever steps to get that off of there. There will
be hundreds of companies that block everything
originating from the listed domains.

No need to ask more than once.

And I don't normally. But, I have posted many times before and never
received a response if it was down a thread. This issue is very serious, so
I wanted it on top.

Thanks for your help.

A little paranoid, aren't we?
