Default relay encrypted transport (TLS)

[Afox]

Hello,
you write "Proxmox Mail Gateway uses opportunistic TLS encryption".

Does this also count for the default relay? So if the default relay has not setup TLS, there won´t be an encrypted transport for incoming mails to this relay?

What about mails that come from the default relay to the PMG?

Regards,

hi again, are my assumptions correct? Is the relay process similar to delivering a mail to an external mailserver?
