so far I've setup multiple postfix instances being final destinations
for one or more domains and I have successfully setup some postfix

No, you use TRANSPORT_MAPS with per-domain entries that deliver

Do address_verification probes work when checking aliased or plus-addressed

E.g.,
I have a REAL address defined,
m...@example.com
address_verification probes work, and the mail's passed.

me+p
