Hello, I have the issue that when I go to send a new mail, I get the
following response Immediately (before it even leaves my computer)...533
Sorry, that domain isn't in my list of allowed rcpthosts. I am using Outlook
2002. I receive email fine. I can even respond (reply) to the emails, but
if I start a new email and use the address from a previously sent mail, it
comes back with that 533 message.

I have disabled my antivirus and firewall (both Norton) and still have the
same issue.

I glanced through the other messages, but didn't find the help there. I
really appreciate any assistance from everyone here.

Thanks, Andy

Usually a sympton of not properly authenicating to the outgoing server.
