[ExchangeList] Error 550 Relaying Mail

Hello all,

 

I'm scratching my head at this one......

 

I've helped a client - Paragoncommunities.com - change over to a new ISP
(Time Warner).  Since Time Warner is hosting their mail and their domain is
now pointing to Time Warner's DNS servers (along with MX record change),
they are now able to send and receive mail.  However, when sending from my
exchange server, I get intermittent relay errors when sending to their
domain.  Here is a transcript:

 

The original message was received at Wed, 11 Oct 2006 10:11:52 -0400 (EDT)
from mail2.csical.com [65.214.152.235]

I've called Time Warner and they said it's a problem on my end.  I'm not
sure I agree because I'm not getting any relaying mail errors to any other
domain in which I send mail.

 

Any ideas?  Thanks for your input, in advance.
