Thunderbird talk to our zimbra mail server need check TLS version. New version of thunderbird only access TLS version 3 and above, but our zimbra version is 1. We need to change Thunderbird config file to fix the problem:

Code:

setting -- search config editor -- set security.tls.version.min to 1

Thunderbird versions
We had a lot of problem configuring thunderbird on centos 8 to talk with our zimbra mail server. I tried to configure openssl config to use MinProtocol = TLSv1 and it works for 'openssl s_client' but does not work with thunrderbird. Finally, I downloaded thunderbird 68.10 from gcp://world/software/thunderbird/ and it appears to work well with our zimbra mail server.

Example location of "opensslcnf.config" : "/etc/crypto-policies/back-ends/"
Note: different version of openssl may change the location of "opensslcnf.config".

thunderbird's GCP is:
gcp://world/software/thunderbird/
