RE: rDNS?

["Dean Hoffman" <dhoffman@xxxxxxxxxxxxxxxxxxx>]

This is something a lot of domains (I got it from AOL) have been
implementing.  This is not an i5 issue.  You have to call your ISP and setup
a reverse DNS entry for the IP address that the outside world sees you as
(for us it was the router's external ip address).  Once that is setup it
should be fine.

Hi all,

Hope someone can give me a hint on this one.

 

I'm currently using an i5 as email server, no domino, just regular old
POP/SMTP.  I've recently been getting "undeliverables" from Comcast email
addresses with the message: 
521 521: Comcast requires that all mail servers must have a PTR record with
a valid Reverse DNS entry. Currently your mailserver does not fill that
requirement. For more information, refer to:

 

Can anyone point me in the right direction to fix this on the i5?
