I just noticed that 43 of our MDOsprey subscribers who are also Comcast
users are having mail from MDOsprey rejected with the following error
message:

 

                            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

 

From past experience I know that the Listserv folks have no patience at all
with Comcast.  Therefore, you might want to be prepared for another mass
extinction of Comcast subscribers here on MDOsprey.  

 

Good luck!
