Version 19.1.2360 mail shield cause problems with Thunderbird

[waclaw66]

The recommended IMAP connection protocol (in many email clients, mail filters, etc.) is SSL/TLS on port 993.

Have you tried this configuration since you have solved the certificate issue?

Yes, as I wrote in the first post, SSL on 993 works normally. But STARTTLS on 143 has been broken since Avast 19.x.

The probem finally disappeared with the latest beta version 19.3.2365 (build 19.3.4213.404).

You really need to create your own new topic, much will have changed in over a year and breathing life into an old topic isn't great.

Give more details (error messages, etc.), your Operating System, Avast version, the version and build numbers ?
