Nothing changed on this end. It connected fine up until Sunday night. But I can't explain why TB successfully connects to Comcast on one system, but not on the other. -----Original Message----- From: Derek Atkins <derek at ihtfp.com> To: epp at vivaldi.net Cc: discuss at blu.org Sent: Wed, 09 Oct 2019 8:32 AM Subject: Re: [Discuss] Thunderbird not connecting to Comcast IMAP server Did anything change on your end? Did you take any updates? Could it be a TLS ciphersuite incompatibility issue? I believe that F30 disabled a BUNCH of old ciphers. If Comcast is running an older IMAP service you might not have compatible ciphers anymore. -derek On Wed, October 9, 2019 8:27 am, epp at vivaldi.net wrote: > Beginning this past Monday, Thunderbird and the SeaMonkey suite (on Fedora > 30) mysteriously stopped connecting to Comcast's IMAP mail server. > > In trying to diagnose the issue, I also installed Evolution, which also > failed to connect. > > After removing the Comcast accounts from Thunderbird, attempts were made > to add them back in, however when Thunderbird attempted to check the > password, that process becomes stuck, as if Thunderbird cannot resolve the > IP address(es) for the Comcast server.
