-o name=value
Override the named main.cf configuration
parameter. The parameter value can refer to
other parameters as $name etc., just like in
main.cf. See postconf(5) for syntax.
NOTE 1: do not specify whitespace around the
"=". In parameter values, either avoid
whitespace altogether, use commas instead of

===>> name=$override_parameter" with $over-
===>> ride_parameter set in main.cf.
NOTE 2: Over-zealous use of parameter over-
rides makes the Postfix configuration hard
to understand and maintain. At a certain
point, it might be easier to configure mul-
tiple instances of Postfix, instead of con-
figuring multiple personalities via mas-
ter.cf.

Finally, no client software cares what your banner says beyond the minimal:
220 server.example.com ESMTP
So banner customization is almost always pointless.
