https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D251327 Christoph Moench-Tegeder <cmt@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|New |Closed Resolution|--- |Works As Intended --- Comment #5 from Christoph Moench-Tegeder <cmt@freebsd.org> --- (In reply to Shane from comment #3) > I have changed the server name to mail.superb.net Aha. Checking that with openssl, I get, among others: - "Protocol : TLSv1" - "Peer signing digest: MD5-SHA1" or, when doing it right[tm]: "openssl s_client -no_ssl3 -no_tls1 -no_tls1_1 -connect mail.superb.net:995" yields "unsupported protocol". May I suggest that your email provider is really behind the curve with their TLS configuration? Not offering TLSv1.2 is so... 2010? Anyways, Mozilla disabled TLS 1.0 and 1.1 in the 78 versions, see release n= otes at https://www.thunderbird.net/en-US/thunderbird/78.0/releasenotes/ . You could use config settings security.tls.version.enable-deprecated and/or security.tls.version.min/max to re-enable the old protocols. Please note: T= HIS IS NOT A RECOMMENDED CONFIGURATION. There's (only slightly outdated) documentation on these settings in http://kb.mozillazine.org/Security.tls.version.* (I can only hope that you don't have any problems with completely unimplemented ciphers or similar, b= ut in the end you really need to talk to your mail host provider). --=20 You are receiving this mail because: You are the assignee for the bug.=
