We Need a custom PTR /Reverse DNS record setup

We Need a custom PTR /Reverse DNS record setup for one of our static IPs because sent mails from our domain are getting bounced back. 

This is per Comcast (http://postmaster.comcast.net/smtp-error-codes.php#BL000010 )  that shows:

"Your email could not be delivered because your email provider is listed on the Cloudmark Sender Intelligence (CSI). CSI is a list of IP addresses which have been detected as sending spam. Comcast uses this list to protect its subscribers from receiving spam."

Current email send server is on 50/250.11.253. 

The reversion DNS/ PTR should display smtp.town.arlington.ma.us.

It is currently showing 50-250-11-253-static.hfc.comcastbusiness.net

Hi! Thanks for reaching out to Comcast over Forums for help with the PTR request. You have reached the right place for help! I definitely understand the importance of having those emails routed correctly for your business! Let’s get that fixed! For security purposes, would you mind deleting your account information and clicking on my handle (Comcast_Gabe) and sending me a private message with your account number, full address, and first/last name?

Our emails are getting rejected because CLoudmark has us blacklisted since our revers DNS/PTR for our Comcast sending IP ( 50.250.11.253) shows a generic Comcast address ( 50-250-11-253-static.hfc.comcastbusiness.net) instead of what it should be smtp.town.arlington.ma.us.

 

Please change the PTR for this to smtp.town.arlington.ma.us.

I can be reached at 508-878-7629 any time
