**COMING SOON**
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.

Port settings can generally be found in your email application's Account Settings, Properties or Preferences section. If your email application is not listed above, please consult your email application developer for instructions on changing your POP account settings.
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.
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.

WITH XFINITY LOGO:
We suggest you update your settings to improve the security of your email service. Since you use an email application (Outlook, Apple Mail, Thunderbird, etc.) with a ‘POP’ setting to access your Comcast.net email, you’ll need to update to your email settings by 9/12/18 so you can continue to receive your Comcast.net email through the application.
I USE THUNDERBIRD for both my e-mail accounts and fear changing Comcast port from 110 DEFAULT used for both will shut down my emails
ANY OTHERS FACED WITH THIS XFINITY INTRUSION?

Could someone from Xfinity please weigh in on this?
It's not a phishing attempt; the email is legit. If you're using an email client you will need to update your settings.

It's not a phishing attempt; the email is legit. If you're using an email client you will need to update your settings.
BUT SEE AT BOTTOM OF XFINITY MESSAGE:
Please note that no changes are required to continue receiving your email through Xfinity Connect Webmail, Xfinity Connect App, or any email application with updated settings. You can always access your webmail by visiting myxfinity.com.
Per above, I use Thunderbird and have another e-mail server in addition to Comcast. I do not want to chance losing both. May be better to dump Comcast than disrupt both servers by changing port!
- Webmail requires no changes.
- The Connect app requires no changes.
- If you're using an email client like Thunderbird with IMAP settings there are no changes.
- If you're using an email client like Thunderbird with POP3 settings, you will need to make the required changes in order to use your @comcast.net email if your settings don't match those in the email you were sent.

When I do this in Outlook I get a server error message:
Got a bad certificate?
~Bob
Doesn't seem like anyone official is following or replying here. I'm shocked! 
And doesn't seem like they tested certificates before rolling this out. Shocked again. Would be nice to get some support for those of us that do not have this working as they expected.

I don't have a Verizon email account. I haven't had Verizon in probably 10 years. If I try switching the save message folder over to the comcast.net folder, I get the same message about the folder being unsuitable.
You may need to do one of two things, then.
1.) Follow the path that is shown in the error message and delete it
OR
2.) Delete the account in Thunderbird and set it up again.
Try #1 first.

I'm using Outlook 2010. Using POP3.
I've tried updating my port settings and i am still not receiving my emails. VERY FRUSTRATING.
I can still receive on my phone without changing any settings.
It appears that if i compose an email, it will send, but none of my emails are being received.
Check the settings on the phone to see if emails are being deleted from the server once they are downloaded to your phone.

My settings are just as they should be and still not receiving ANY emails.
I made the changes to ports and setting back in October and everything has been working perfectly, until today. Suddenly I cannot log into the POP3 server (pop3.comcast.net) using port 995 and SSL (via Outlook). I am told:
"Your server does not support the connection encryption type you have specified."
This leads me to believe the issue is on xfinity's side. Working yesterday, nothing changed, not working today. Hard to think it's on my end
