Thanks Scott and Len,
It looks like that helped and fixed the problem. Doing it this way is just
one extra click of a button for users when setting up their email clients on
IE anyway.
I am going to watch the log files for the next few days, but I expect great
results.
Oh, you are so right about the manual and the defaults. The manual made me
think that somehow it was authenticating. I thought that from local users
meant that it checked the user name and password before sending. I did not
realize that it was not happening that way until I posted to you guys.
Thanks for the info on that...
Thanks again!
Patrick

Sounds like a spammer.

That means that you allow people claiming to be from one of your hosts to
relay. That means you allow anyone who is willing to lie to relay.

><[EMAIL PROTECTED]>... Sender domain must resolve
This one means that when your mail server sent the spam, the remote computer
rejected it because the "From:" address comes from an invalid domain. With
Declude you could have rejected it, either for outgoing or incoming mail.
You want to use "Relay for Addresses" and SMTP AUTH.
