Thank you for your continued assistance.
Support from the Server company states the following.
"Why doesn't the mail server let me send messages from a script?
As an anti-SPAM measure, mail servers you use to send mail from your mail clients (like Outlook Express) are no longer set up to accept mail from your scripts and applications (like FrontPage, SharePoint and Miva).
To be able to send mail from scripts and applications you must change the mail server from "mail.your_domain.name" to "scriptmail.intermedia.net".
There are three main conditions to use scriptmail.intermedia.net:
1. Mail should be send from scripts located on Intermedia Web servers or from FrontPage, SharePoint and Miva applications hosted by Intermedia.
2. The domain name in either FROM address *or* all recipient addresses (TO, CC and BCC) must be registered on your account with Intermedia.
3. Domain in your FROM and all recipient addresses should be globally registered in DNS (we check for A or MX records)."

I apologize if I am beating a "dead horse," here. But, is "mail.your_domain.name" somehow referenced or set within MLM files?
Fwiw, I have successfully installed and run MLM on a different server. But my client's server is apparently picky.
Thanks,
Tim
