Cannt send to hotmail or msn accounts

Please help!!!! I cannot send to hotmail or msn accounts on my computer. My
environment is SBS 2003. We use Exchange and have tested sending to hotmail
and msn accounts on other machines. We have even added my e-mail account on
another computer and it sends fine. We have checked the logs and the emails
get sent. We have upgraded to VISTA but I was having these problems before
the upgrade. Any suggestions?

Thanks!

Does IP address of your mail server have a valid reverse DNS entry? MSN and
Hotmail (as well as other providers) will not accept mail from you if you do
not.

Go to www.dnsstuff.com and the second test in the middle column is the
Reverse DNS lookup test. Enter the public IP address of your mail server
and click the RevDNS button and make sure it comes up correctly and matches
the forward DNS (i.e. mail.company.com).
