When I try to send an email to domain.com I receive the follow error:

The following recipient(s) could not be reached:
name@domain.com on 9/6/2010 2:52 PM
You do not have permission to send to this recipient. For assistance, contact your system administrator.
<servername.mydomain.com #4.7.1 smtp;421 4.7.1 <name@domain.com>: Recipient address rejected: No reverse DNS for 65.83.57.35. (c)

I am told the IP address referenced in the error is a netscreen router. My isp is microsoft exchange hosted services, they say they an't help me bcause its not their IP address. My exchange server is 65.83.57.34.

Can I simply add 65.83.57.35 to a reverse dns list onmy exchange server to prevent the NDRs?
