No, there's always somebody that you have to connect through, so that's not
the issue. And it has nothing to do with you using a Macintosh.
Rather than try to figure out where the problem is, let me try to tell you
what needs to happen:
1) The Exchange server needs to have a permanent IP address. If you want to
use a domain name for your POP server, you need to arrange with your ISP for
a DNS record which links your Exchange server's IP address to a fully
qualified domain name (like mail.mydomain.com).
2) If there is a firewall between the Exchange server and the Internet (and
there better be!), you need to open port 110 for POP3 and port 143 for IMAP,
and link the internal LAN's IP address of the Exchange server to the
external IP address.
3) You need to turn on POP3 serving in Exchange, and/or IMAP4 serving. It
doesn't matter if it's retrieving mail via POP3 as well.
4) After all that, you can put the fully qualified domain name into your
mail client as the POP3 server (or the IMAP server, as you prefer).
5) One interesting quirk of Exchange is what they may require for usernames.
Sometimes they're quite happy to use the simple network username, but
sometimes they want something more complex. If your account has a username
and an Exchange alias that are different, you need to enter your account
name in this form:
[WindowsNT Domain]/[WindowsNT Username]/[Exchange Alias]
And here come the guesses: <smile>
Since you say other users can access Exchange's Outlook Web Access
interface, that step 1 is done.
Step 2 may be done, since you can send mail through the Exchange server, but
it may not. The ports are different, and though 25 may be open for sending,
110 may be closed to receiving mail.
Step 3 may or may not be done.
Feel free to email me directly with information about your domain name and
IP addresses; I'd be happy to help you track it down.
