You need to have a PTR record for Reverse DNS on 216.173.234.20 to point
back to a valid domain name. If you maintain your own DNS, you can do
this. If your ISP maintains DNS, ask them.

Subject: [THIN] OT: DNS issue
I am not a DNS guru by any means and we are having some DNS issues with
our email. Some users send emails to other companies and some of them
are getting returned with the following message.
You do not have permission to send to this recipient. For assistance,
contact your system administrator.
<net1ex1.VDINET1 #5.7.1 smtp;554 5.7.1 The server sending your mail
[216.173.234.20] does not have a reverse DNS entry. Connection Rejected.
Please contact your Dial-Up/DSL/Network ISP Provider. Default Reject!>
The ip address given is our firewall. I am not sure what i am needing
to setup here. any help from you pros out there would be most
appreciated.
Thanks,
