Win2k Server and clients.
When I log in locally to a machine I can send e-mail (OE
clients) without a problem. When I log into the domain I
get various unknown error messages when trying to send,
plus this one "the server responded 503.5.5.2 waiting for
rcpt command" Occassionaly, if I select Tools-recieve
all", I can send an e-mail. The error messages do not
mention 550 or relaying.

We are hosting our e-mail externally, we can get incoming
pop mail without a problem and our isp has told us
multiple times that they are not blocking port 25.
Our firewall show smtp going out with no problems.

Any Ideas, Is something messed up in AD ?

Thanks
 
Can you turn on diagnostic logging for SMTP and post the smtplog.txt file
after this happens?
