Relay messages by the Fallback-server

[EdwardDekker]

Hi,

I working on a project to relay my messages from a fallback server to a MX1 server.
And need the relay settings of Plesk for Postfix main.cf file

I send my "/var/spool/postfix/plesk" folder to the fallback server every 15 minutes by rsync.
I'll want to use the settings of Plesk to relay the e-mail to the fallback-server.

These are my settings and need some improvements to let it working for a good relay.
