We currently host internal Exhange and POP/SMTP from Outlook 2003 desktop for

send to hotmail or msn domains...and a few other domains are
sketchy/intermittent. 95% of all our other email sends fine. When the email
gets returned I see an error similar to the following; (mail username has
been changed)

First thing to look at: Do you have a PTR record in DNS for your
sending mail server?


Reporting-MTA: dns;smtp.nexicom.net

Final-Recipient: rfc822;user@xxxxxxx
Action: delayed
Status: 4.4.7
Will-Retry-Until: Sat, 25 Nov 2006 16:04:02 -0500
X-Display-Name: user@xxxxxxx

It does eventually fail with; (yes this is different failed message than
above)

'user@xxxxxxxxxxx' on 11/23/2006 2:12 PM
Could not deliver the message in the time limit specified.
Please retry or contact your administrator.
<smtp.nexicom.net #4.4.7>

Our ISP says it is our Exchange server bouncing the messages as he see's this;

postmaster@xxxxxxxxxxxxxxxxx (names changed by me)

I have checked many KB's and can't come up with anything....like I said
above...hotmail and msn are the two causing the worst headache.

Thanks in advance.
