Re: HELP! SMTP for IMAP stopped working

There's no need to do that at all, though. You can easily connect a remote
computer using RPC over HTTP. You could do it for them via remote control
software in a matter of minutes. Seriously, this is the way to go.

so they use IMAP.
Update if I am on the LAN I can send to internal and external address
- it is only outside users who can not send to external address...

If the authentication was unsuccessful wouldn't I get an error?

Can you refer to me any article on how to test with the telnet
command?

Google should yield a lot of results, but I can't think of any way to test
it *with* authentication via telnet - just the opposite (see if it insists).

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.
