EarthLink IMAP, POP & SMTP Settings

For most EarthLink email apps, use IMAP at imap.earthlink.net:993 with SSL/TLS and outgoing SMTP at smtpauth.earthlink.net:587 with STARTTLS. Use your full email address and password for both incoming and outgoing authentication. EarthLink recommends IMAP when you want messages synchronized with WebMail and other IMAP clients.

For both servers, EarthLink says to use the complete email address and its password. Do not use your password on TCSWebmail.org; enter it only in your mail app or an official EarthLink sign-in.

When should you use POP3?

POP3 is an older option. EarthLink’s general settings use port 995 with SSL/TLS; the incoming host is domain-specific, such as pop.earthlink.net or pop.mindspring.com. The outgoing server remains smtpauth.earthlink.net on port 587 with STARTTLS.

POP apps may download messages from the server. If you want downloaded messages to remain visible in WebMail, look for the mail app’s “Leave a copy of messages on the server” option. IMAP is usually the simpler choice when you read the same mailbox on several devices.

Setup and troubleshooting

Use the full email address as the username if the app requests one. If a device cannot connect, verify the incoming and outgoing server names, port, encryption mode, and password before changing other security settings. Some EarthLink domains have domain-specific POP hosts, so confirm the exact address in EarthLink’s current settings page.

See EarthLink email setup in Outlook for the account-add flow, or choose between WebMail and HostingMail if your address uses a hosted domain.
