The iPhone supports automated setups for Microsoft Exchange, iCloud Mail, Gmail, Yahoo Mail and AOL, so to sync your Road Runner mailbox with the Mail app in iOS, you must configure your account manually. Along with your email address and password, you'll need to know the address of the incoming mail server that's used to download messages stored in your inbox, as well as the address of the outgoing mail server used to route your sent messages to the appropriate recipients. The addresses of your mail servers vary depending on your service location.
Touch the "Settings" icon on the Home or Apps screen, and then select "Mail, Contacts, Calendars."
Touch "Add Account," and then choose "Other" from the list of providers.
Touch "Add Mail Account," and then enter your display name, email address and password into the corresponding fields. Touch "Next."
Enter "mail.twc.com" (without quotation marks) into the Host Name field under the Incoming Mail Server section, and then re-enter your email address and password into the Username and Password fields.
Enter "mail.twc.com" (without quotation marks) into the Host Name field under the Outgoing Mail Server section, and then re-enter your email address and password into the Username and Password fields.
Touch "Next" to add your Road Runner account to your iPhone, and then toggle "Mail" to "On" to sync your mailbox with your device.
Press "Save" to apply your settings and complete the setup wizard.
If your email address ends in "rr.com," use the address "pop-server.location.rr.com" for the incoming mail server and "smtp-server.location.rr.com" for the outgoing mail server, replacing "location" with your area of service -- you should see this location in your email address as well. For example, if you're in central Florida, use the incoming mail server "pop-server.cfl.rr.com" and the outgoing mail server "smtp-server.cfl.rr.com."
