I am having problems with emails for certain domains getting stuck in the
mailq with 5210R. Not had this error in other BX versions.
The server is using a Letsencrypt certificate, and the visite has it's own
Letsencrypt certificate. There is only one visite on the server. Most users
are sending via smtp AUTH.
The error says:
Deferred: 403 4.7.0 TLS handshake failed
I can get around it by adding a TLS exemption in /etc/mail/access for the
But I can't be sitting there all day looking out for handshake failing
domains to bypass. I would like to diagnose the problem, but don't know
where to start. Any suggestions?
