This doesn't happen often but I got a bounceback today from a comcast mail account that said this:
#< #5.0.0 smtp; 554 imta04.emeryville.ca.mail.
t comcast 188.8.131.52 Comcast requires that all mail servers must have a PTR record with a valid Reverse DNS entry. Currently your mail server does not fill that requirement. For more information, refer to: http://help.comcast.net/content/faq/PTR
I need to know where to look up this record and how to find out if my mail server is kosher. Other than this I dont have any issues.
Running SBS 2008 R2 with Exchange 07. File server / mail server.
Thank you for your help in advance.
