After upgrading to version 78.2.2 this morning, am no longer syncing with the Hughes.Net satellite. Can not send or receive. Send Error Message states 'Peer using unsupported version of security protocol'.

What are your settings? The ones given here seem to have worked in the past, although some sources suggest mail.hughes.net for the incoming server.

The mail server appears to support TLS 1.2, so you shouldn't need to make the change indicated in the other topic, so I don't know why you get the error. You may have to change the preference security.tls.version.enable-deprecated to true as suggested by another user in that topic. What is your security/AV app?
