Shouldn't this mailserver make relay decisions based on IP?

---/etc/postfix/canonical-recipients:
gmxusergmx.de userA
tonlineusert-online.de userB

if recipient is a local User, we avoid using the provider

---/etc/postfix/canonical-sender
userAmyhostname.mydomain gmxusergmx.de
userBmyhostname.mydomain tonlineusert-online.de

replace local addresses by correct addresses for the provider

---/etc/postfix/transport
myhostname.mydomain local:

local mail is supposed to be delivered locally

soft_bounce = yes
Enable soft bounces in case one of the providers refuses badly addressed
email.
