What mail clients are they using? SPA uses NTLM auth under the covers, so
users will need an SPA compliant mail client.

Secondly, POP3 and SMTP auth are two separate things.
When you do "send and receive", you need to auth to the POP3 server, and you
need to auth to the SMTP server.

Now, it seems that your email client is somehow "loosing" it's settings (and
so trying to logon anonymously), which is probably why the user is getting a
prompt. You could verify this by using ethereal (www.ethereal.com) and
putting a trace on the network (I'm happy to have a quite look at the trace
output if you want).

If this is the case (OE forgets settings, and tries to logon anonymously),
then this is an OE issue, not an SMTP server issue...

: I run a Win2k3 server with iis 6.0 and standard pop3 with smtp. The issue
I'm facing is that my customers who use the server to send messages keep
getting a pop up box asking for their username and password credentials when
I set the smtp server to use Integrated Windows Authenication and Anonymous.
When I use Basic Authenication, this goes away but I'm exposed with clear
text over the Internet. Any ideas on how to patch this? I want to be secured
with that info when it travels to the server.

: I have SPA unchecked on the server and I even tried checking the SPA in
outgoing for Outlook Express. When I tested this senerio, it asked for
credentials the first time only but then the setting became unchecked when I
went back into the mail profile under the outgoing authenication settings.

: Any info would be appreciated.
