Roadrunner Email Server Settings: IMAP, POP3 and SMTP
One page. Every server, every port. This is the reference I wish existed when I first had to migrate an old Roadrunner account.
Quick answer: The Roadrunner email server settings are IMAP mobile.charter.net port 993, POP3 pop.charter.net port 995, and SMTP mobile.charter.net port 587, all with SSL on and your full address as the username.
IMAP and SMTP (recommended)
POP3 (only if you need it)
These apply across the whole Roadrunner family of addresses, which is wider than people expect. rr.com, roadrunner.com, twc.com and brighthouse.com all run on the same Spectrum servers now.
A note from experience. If a device has mail.twc.com saved and it still sends and receives, you do not have to touch it. That older server continues to answer for rr.com mail. For anything new, use mobile.charter.net.
Keep this handy. You will reach for it every time you add the account to another phone or app.
If you reach the limit of what settings can fix, the account itself is managed by Spectrum. The Spectrum webmail sign-in and the official settings page are where to go next.
Questions people ask
Do rr.com and roadrunner.com use different servers?
No. They share the same Spectrum servers. One set of settings covers rr.com, roadrunner.com, twc.com and brighthouse.com.
Is mail.twc.com still valid?
Yes, for existing rr.com setups it still answers. For anything new, use mobile.charter.net, the current Spectrum server.
Which protocol should most people pick?
IMAP. Every time, unless you have a specific reason not to. It keeps all your devices in sync and leaves mail safely on the server. POP is the niche choice, not the default.
