[BlueOnyx:25474] TLS on 5210R

[Colin Jack]

Good afternoon,

I have recently moved one of my mail relay servers from 5209R to 5210R.
Now any clients using TLS are unable to send mail. Disabling TLS fixes the problem.

We have a valid LE cert on the server.

What have I missed?

Clients are using SMTPAuth and submission port 587 for mail.

Thanks

Colin
