Our old mailserver works only with Thundrbird version 68.11
The incoming mail stopped coming after the Automatic update of Thunderbird. Our old Mail-server does not understand the new versions. I can download the Old Thunderbird version 68.11 and I can import the contacts. I can not import the filters because there is a fault in version 68.11 because it wants to import LOCAL MAIL instead of FILTERS. How can I prevent Thunderbird from updating to a newer version ?
