As we all know that not really easily done. I might consider a mail
"ham" while other systems consider the mail to be "spam".

The first step must be to check HOW MANY mails are bouncing at all.

A big percentage? And then one needs to check the anti spam methods
one is using. And compare them to the checks the "real" recipient is
using.

Did the OP show "postconf -n" yet?

That's probably the simplest solution :)
