Residential Mail System Servers


Customers on our Residential Mail System will have an email address ending in either @twc.com, @roadrunner.com or @something.rr.com (e.g., @ca.rr.com, @austin.rr.com, etc.); no customers have an address ending in @rr.com, as that domain is reserved solely for role accounts.

The inbound hosts (MX records) for all Residential domains follow:

  • cdptpa-pub-iedge-vip.email.rr.com
  • dnvrco-pub-iedge-vip.email.rr.com

The outbound mail servers for normal customer mail for our Residential Mail System are located in the following two networks:

  • 107.14.73.[225-232]
  • 107.14.166.[225-232]
