What you want is part of a slippery slope that ends up where
one Postfix instance implements multiple personalities:

- the SMTP server greets with an MTA personality that depends on
server IP address,

- delivery errors are reported with an MTA personality that depends
on the recipient domain,

- delivery agents send mail with a source IP address that depends
on the client or sender identity.

- and so on.

This will not happen.

If you want multiple MTA personalities, then you must use multiple
MTA instances.
