Enabling IMAP on exchange server 2003

Ok, so we've established that it will send using SMTP. However, it still doesnt work. I can't send messages. I've enabled explicitly that my account should be able to authenticate remotely in the exchange system manager, but it still won't let me send remotely (using outlook express).

Its not a basic settings problem. I've selected 'my server requires authentication' and Im using the same credentials that Im using to download messages, which is working. Im sure its a configuration issue on the exchange server, but I dont know what Im missing.

Here is Sembee's guide on how to configure (or rather, secure) an SMTP Relay server;

That should give you the steps you need to do this properly.

I'll take a look at that. Its worth mentioning at this point that if I send to local addresses, it works fine. It only fails if I try to send to an external host (yahoo, gmail) - so it appears the main problem is that its treating any mail I try to send as local.

I'll read the link and report back.

Yeah, I looked at the link. I've already done this. My account explicitly has submit and relay permissions. If it doesnt work for a single user, its not going to work for a security group either.

I just think its odd that it can send to local accounts, but not remote accounts.

Sending locally is a sign that authenticated relaying is the problem.

It thinks you are relaying - by default, anyone can send to local accounts, so there is nothing strange there.

I would create a brand new account called test123, with the email address of test123

Then try and authenticate (using outlook express or something).

The only other thing I am thinking of off the top of my head is the authentication settings on the SMTP server - open Exchange System Manager, Drill down to your server, protocols, smtp, right click on the default smtp server, properties, and now look for the authentication settings (i am tired, and can;t remember off the top of my head).

In there, you want to have Anonymous and Basic ticked.

"In there, you want to have Anonymous and Basic ticked"

Yeah, they are both selected. I just dont understand why its not going ahead and relaying the message. My account is set up explicitly to allow relay, and even the security group that Im a member of is as well.
