Could this be an anti-virus issue all of a sudden?

Sure, I suppose so.

Or maybe not
successfully authenticating?

That's what it sounds like. Check the client, I guess. Try a telnet session.

I don't allow relay on my servers, so I'm not sure what else you can check,
sorry. What's the reason you're using this instead of RPC over HTTP? For Mac
users there's Entourage 2008 (or 2004, which is not quite as good).

HELP!

Have you tested yourself using OE on a LAN-connected computer?
Have you checked to ensure the authenticated relay settings are
still as you wish in the properties of your virtual SMTP server?

FWIW, I wouldn't enable IMAP (although it's a sight better than
POP3). Internal and external users can use Outlook/MAPI connections
to the mailbox, the external ones via RPC over HTTP. No relay is
needed. Using Exchange for IMAP is kind of a waste.


No settings have changed that I can find - after further testing I
can send to users who have an exchange mailbox just not external
addresses.
Thanks

Double check the SMTP virtual server for its relay settings.
Something is not set up right in there.
