I hear ya, but unfortunately if you install Office/Outlook 2003 (no service
packs or updates) you will quickly find yourself with a receding hairline in
trying to get SSL/TLS over port 587 working. One *must* apply Office 2003
Service Pack 2 in order to get this working right.
As for Exchange 2003, I generally setup 2 SMTP virtual servers when
IMAP/POP3/SMTP support is a requirement. SMTP VS1 is for anonymous inbound
only connections on port 25. SMTP VS2 is for authenticated TLS/SSL
connections on 587. Unfortunately there is no way in Exchange to say it
will only accept connections on port 25 from other MTAs. If it did, Rolex
wouldn't get the e-mail coverage it does today. ;)
Outside of that and if you can get away with it, try to persuade the site to
go with RPC over HTTPs. This method of connection to Exchange 2003 is far
superior than any IMAP/POP3 session. Only draw back is that it is only for
Windows XP/Office 2003 platform or newer.

neo,
Port 587 is NOT a non-standard port. It is the OFFICAL port that MUA
should
be sending mail to. MUA should not be sending mail to port 25 as that's
for
MTA to MTA. I know it used to be that way but since the new RFC was
approved
several years ago everyone should be switching to the MSA port 587.
What I'd like to know is if Exchange will fully support MSA functions? I'd
also like to know if you can block users from sending mail through port
25?
The only thing I want coming in to port 25 is mail from MTAs. I don't want
users using that port at all.

Most likely this question has more to do with verifying the Microsoft
Exchange Server configuration and not Microsoft Outlook. In any case,
can
you post the version numbers of each? You should also state if the users
are using their ISP's SMTP server or your Exchange server to send
messages.
If your server, are the clients connecting to your SMTP server on port 25
or
a non-standard port like 465 or 587.

We have an exchange server, all my users are a remote users and using
POP3
services that means all the users are using different ISP's. If I
sent
an
email to the outside user I get a reply back as
Your message did not reach some or all of the intended recipients.

The following recipient(s) could not be reached:
Yet if I sent an email to some one on the same domain it reaches it's
destination without any problems. It tells me that the the mail
services
reached all the way to my mail server and it refused to send email out
because it did not know the source. How can I get my outlook to send
using exchange servers services without opening myself to open relay
situation.
