Introduction

This article applies to Comcast Business customers using residential email addresses.

To better protect email and Xfinity credentials from being compromised, customers who use a third party email application (Outlook, Apple Mail, Thunderbird, etc.) through a POP connection are now required to use a secure mail server and can no longer utilize POP Port 110. While POP will still be supported, customers should ensure that their email application is set up through the secure Port 995.

If your application is configured through Port 110, you’ll need to make a few updates to continue to using your Xfinity email. Please locate your email application below for instructions on changing your port settings.

Frequently asked questions

Why is access to email through Port 110 being blocked?
We are blocking this port because it is not encrypted and may leave your email account information vulnerable to being compromised. No accounts have been compromised; however, this change will help to provide you and your personal information with the best level of protection possible.

Can I still access my email through POP?
Yes. Port 995 with SSL is secure and is the recommended port for POP. You can update your Incoming Mail Server Port to 995 with SSL to continue to receive mail without any change to your experience.

Will changing the email settings affect how I receive emails or manage my mailbox?
We recommend that you switch from POP Port 110 to Port 995, which will not affect how you receive emails or manage your mailbox.

If you wish to change from POP to IMAP, please move any emails or folders that you wish to save into your new IMAP account before deleting the POP account to prevent any impact to your experience. Please see Switching from POP to IMAP for additional details.

What will happen if I do not update my port settings?
After access to the port is blocked, you will receive an error message in your third party email application when attempting to access your Xfinity email. You will continue to be able to access your email through Xfinity Connect webmail, the Xfinity Connect app or any email application without any impact.

When do I need to make these updates?
Please update your settings prior to November 2018 to ensure that you can continue using email with your third party email application after Port 110 is blocked.

If you update your settings after port access has been blocked, any email received while blocked will appear in your inbox once you have updated your port settings.
