Since Thunderbird was upgraded to 115.10.1 (64-bit), it now fails to send SMTP messages with the following error.
Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) ***.mail.pairserver.com was lost in the middle of the transaction. Try again.
This affects all six(6) accounts in Thunderbird, all of them can receive and edit e-mail messages; however, all of them fail to send e-mail messages.
Prior versions of Thunderbird have worked with this configuration for many years.
Other e-mail clients such as Evolution do not have this issue and I have confirmed with my provider that Thunderbird is no longer sending e-mails.
Any thoughts on how to roll back Thunderbird until this issue is resolved?
