IMAP makes it easier to sync your email on multiple devices because your folders and mail remain on our server until you move or delete them with your device. POP can cause problems when checking your mail from more than one phone or computer because POP removes the mail from our server and delivers it to your device. We recommend using IMAP for your Comcast email. IMAP: POP (Post Office Protocol) and IMAP (Internet Message Access Protocol) are two different ways to get email in your email program. If you're using an older email program like Outlook Express, Outlook, or Mac Mail, you may have trouble sending email. To protect your security and help prevent spam, we no longer support port 25. Port Numbers: Your email port is how email moves from one email server to another. When you're setting up your email account, your program will ask for some information about email 'protocols.' Here are a couple of things to know as part of your set-up:

Authentication: Type in your Comcast username and passwordĮmail Setup: Port Numbers and POP vs.

Encryption: TLS (use SSL if TLS isn't shown.).

Outgoing Mail Server Port Number: 587 (SMTP).

If the Mail Client lets you select an authentication method, choose STARTTLS.

Incoming Mail Server Port Number: 993 with SSL ON.

When your program asks you to set up your email, use these settings to connect your Comcast email: We recommend you access your Comcast email by going to Xfinity Connect and clicking Email, or by using the Xfinity Connect app on your mobile device. Using third-party email clients (e.g., Outlook, Apple Mail, Thunderbird, etc.) to access your email address can potentially expose your Xfinity ID and password to fraud and other risks. If you use an older email client (Outlook Express, Outlook, Mac Mail, etc.), this might impact your ability to send email.

To ensure the security of our network and customers, we no longer support the use of port 25 for sending email.

Just head to the links section and pick your program. If you have questions about your specific program or email client, we've got you covered. But if you prefer using an email program instead, these settings will have you up and running in no time! Our web-based Xfinity Connect page and app come set up and ready for you to use.
