Support XFINITY Internet Using Email Client Programs with Comcast Email

Introduction

To prevent spam and to ensure the security of our network and customers, Comcast no longer supports the use of port 25 for sending email. If you use an older email client (Outlook Express, Outlook, Mac Mail, etc.), this may impact your ability to send email. To learn more about port 25, please visit our FAQ.

To configure an email client to use Comcast email (@comcast.net), the following settings should be used for sending and receiving email:


Recommended Only If Needed
Incoming Mail Server - Name mail.comcast.net mail.comcast.net
Incoming Mail Server - Port Number 995 (POP3) 110 (POP3)
Outgoing Mail Server - Name smtp.comcast.net smtp.comcast.net
Outgoing Mail Server - Port Number 587 (SMTP) 465 (SMTPS)
SSL Encryption checked checked
Authentication Comcast ID and Password required
