Hi forum!

I am trying to establish the following:

2 Hetzner-Cloudservers.

One with PMG the other with Grommunio Mailserver (MS-Exchange Clone)

The goal is to send the incoming mail traffic for all the maildomains hosted on the grommunio through pmg and to send the outgoing traffic through pmg.
Pmg should also manage creation and extension the letsencrypt certificates. And offer them for autodiscover ms outlook.

Is that possible at all?

Are there any how tos or something like that to read?

Thank you very much for your tips!
