Looking at this closely. I found couple of strange things

charite.de OK
<> OK

what does <> mean? can is use relay_domain db instead? it does not
have <> but I wonder if should add it to relay_domains to use a
single file


Also

can /etc/postfix/internal_networks be replaced mynetworks?


Another one with the list of all my domains

/etc/postfix/not_our_domain_as_sender:
charite.de 554 Bloody liar!


Looks like I will have to create a little bash script to generate this
files instead is this a good idea?
thanks.

<> is the "smtpd_null_access_lookup_key", see:

$ postconf -d smtpd_null_access_lookup_key
smtpd_null_access_lookup_key = <>

No.

I added "<>" in order to allow bounces back out!

Sort of, yes. The right hand side must be "has_our_domain_as_sender",
though.
