To set up your rr.com email login in third-party email clients like Outlook, Apple Mail, or Thunderbird, you’ll need the correct IMAP, SMTP, or POP settings. For most users, IMAP is recommended because it syncs your emails across all devices. If you prefer POP, set the POP server to mail twc com, port 995, and turn on SSL. In your client’s settings, make sure “Outgoing server requires authentication” is checked and uses the same credentials as incoming mail. Once configured, test sending and receiving emails to confirm everything works. These settings apply to most legacy domains under Roadrunner and ensure a smooth connection with your preferred email app.
