You tested someone else's domain at abuse.net without permission? You do
I highly recommend going to one of the sites like mailabuse.org and
following their directions to verify that you're not an open relay BEFORE
you get blacklisted. It can be a real pain to get off all the blacklists,
and your users will scream bloody murder.

I've tested via telnet and from home using Outlook Express and it always
replies with 550 so I think I'm good there. Just the amount of mail is
insane. I came in this morning
on the servers, in order to justify new servers.

Open up the properties page of your IMS Connection, go
Your best solution is to find out the source of those messages, and then

relay attempt during the RCPT TO: command, so the messages won't be accepted
for delivery and therefore they won't be NDRed.
2. Yes.
3. If dfg.com is your domain then it's normal spam to automatically
