Ok, I don't use either IIS or Exchange, both of which I feel are too
insecure, so take everything I'm about to say with a grain of salt. (if you
care, I use apache and qmail instead)

Please provide us with a link to the docs you're using so that we can help
narrow down the problem.

Yahoo uses qmail as you can see by the format of the error message above.
Please telnet into port 25 and test the connection manually.

Uh, no you haven't IIS doesn't have anything to do with those, you're
thinking exchange.

Is that your exchange server or an SMTP at your ISP?

Then something is wrong with your pop3 setup.

What is listening on port 110?

DNS would be a good thing if you're trying to run an email server, how else
are you going to handle MX records? Check here for IMS info:

Not necessarily, depends on how it's coded.

I highly recommend taking this question to an Exchange server mailing list,
you'll get much better answers.
