Well, show some evidence.

I thought this is a system that should move mails as fast as possible
outgoing. Why would it ever handle bounces?

Authentication?

Don't use that.

Only listen on localhost. So you actually have the application and
postfix battling on ressources on this system? Why?

You can't send such long lines, ever!

This does not make sense.
