Sorry I wasn't clear. It's not users in my domain, it's the Hotmail or AOL accounts that are getting bounces.
Here is one of the bounces I had forwarded to my Hotmail account. Please note that when I attempt to send from my Hotmail, it's fine. So this does not seem to affect every account. MIME-Version: 1.0 Received: from mow-m25 (mow-m25.webmail.aol.com [64.12.137.2]) by air-id09.mx.aol.com (v83.45) with ESMTP id MAILINID94-0315173006; Fri, 15 Mar 2002 17:30:06 -0500 Return-Path: <[EMAIL PROTECTED]> X-Mailer: Unknown (No Version) Message-ID: <[EMAIL PROTECTED]> The original message was received at Fri, 15 Mar 2002 16:36:49 -0500 (EST) from root@localhost ----- The following addresses had permanent fatal errors ----- <[EMAIL PROTECTED]> ----- Transcript of session follows ----- .. while talking to myfirewall.mydomain.com.: >>> DATA <<< 554 Invalid data in message 554 <[EMAIL PROTECTED]>...

Regards Mr Louis Joyce Data Support Analyst BT Ignite eSolutions -----Original Message----- From: Whitlock, Teresa [mailto:[EMAIL PROTECTED]] Sent: 19 March 2002 16:57 To: Exchange Discussions Subject: 554 Invalid data in message I'm starting to get some complaints from certain AOL and Hotmail accounts that email is bouncing. I can send fine with my email, but I was forwarded some of the bounced emails with the following message in the header: 554 Invalid data in message Can anyone help point me in a good direction to try to figure out what the heck is happening?
