why does Frontier no longer support Thunderbird?
starting at about 9 AM, Eastern, today - I can no longer get email. Using Thunderbird with Comcast/Xfinity connection.
Chosen solution
Check your Thunderbird e-mail settings to what Comcast/Xfinity wants:
https://www.xfinity.com/support/internet/email-client-programs-with-xfinity-email/
Make sure you are using IMAP with SSL. If you have all the settings correct, contact Comcast.
In Thunderbird, right-click the account and choose "Settings".
For incoming e-mail: Select "Server Settings" on the left side under your e-mail account, and the settings are on the right side.
For outgoing e-mail: Select "Outgoing Server (SMTP)" on the left side, then select the server you want on the right side. Click the "Edit" button to change the settings.

Also, have you updated your e-mail security like Frontier asked you to?
