Right after upgrade ubuntu to 18.04 from 16.??. Using thunderbird 60.8.0. Original POP settings to a comcast server. Current settings: Incoming - POP mail server, server name mail.comcast.net, port 995. Outgoing - smtp.comcast.net, port 465.

Fixed it. Found this solution.

Comcast servers will not except IPv6.... Disable it in Thunderbird: Here's how: in Thunderbird, goto Edit>Preferences>General Tab. On the General screen, select "advanced" tab > "General" subtab, and in the lower right corner find the button "Config Editor" Click on it, acknowledge the warning, and scroll a long ways down to: network.dns.disableIPv6 (default: false) Double-click on the line, and the value will change to "true" Back out and Okay, shut down and restart Thunderbird, and your client will connect to the imap server in a flash.

it's not that they will not accept ipv6. it is that Ubuntu has a bug.
