I am using Windows 2000 Adv Server SP4, IIS 5 and Exchange 2000 SP3.  I have
two servers set up to take care of the mail.  One is an SMTP\SPAM server tha
t
checks messages for SPAM and then forwards them on to the Exchange server.
When users send mail it flows the opposite way.

I recently found out I am providing relaying on the Internet.  I followed
the "Article ID: 310356 HOW TO: Prevent mail relay in the IIS 5.0 SMTP serve
r
in Windows 2000"  When I disabled anonymous access though, the relay was
stopped but no mail was able to flow.  When I allowed anonymous access mail
flowed but the relay was re-enabled.

Is there a way to disable anonymous access while still allowing external
mail to flow?

Thanks.
