Hi Mark,

To send, seems odd as I;ve just found out that other sites setup to use
pop3 the exact same way work, just one site having an issue.

Hi NG,

Our exchange server was configured to send mail to our ISP as a smart
host.
I have just modified our exchange server to use an IIS server we have in
our
DMZ to act as a smart host, our firewall (incoming) SMTP rule was also
changed to forward mail to our new IIS server in the DMZ, all looked
well.

But, our POP3 users (external) cannot autherticate anymore?

Any ideas why this would be?

Cannot authenticate to receive or to send?
