incoming mail works. outgoing mail does not.

[SJBohm]

Here is my current situation:

1. I send an e-mail from my client desktop through the Exchange server.

2. The Exchange server connects to the remote host (with the SMTP server), and initiates a dialog to send the mail.

3. The mail does not go through, and it sits in the Outgoing Queue on the server.

4. In looking at the logs, an actual connection was made, and got all the way to the point of the remote host waiting for the DATA part of the e-mail (the To and From addresses are validated already).

5. Why won't my server send the rest of the e-mail? There aren't any actual error logs, but when I stop and restart the IMS, it kicks back messages saying "Your e-mail is still sitting in the queue."

Any help/advice/answers are much appreciated! Thanks!

r u relaying? or u have an mx....
can u send mail using a client like outlook bypassing the exchange smtp function?

I'll try to answer your questions as best I can. As far as I know, we don't have an MX record. Actually we do, but it's not for our Exchange server. The MX record for our domain points to a server at our ISP, which then holds our e-mail and then we use EFS to download our e-mail from the ISP to our server. Exchange then handles the routing of all the e-mail to the user accounts. I am not relaying anything through our server either. I've read a little about the NDR attacks, but it doesn't seem like we're getting those because in the past two days, I've only had one e-mail sitting in the queue that didn't have an originator.

Thanks,
Steve
