Cleanup: postconf finally supports dynamic configuration
parameter names: parameters whose name depend on a mail
delivery transport name in master.cf, and parameters whose
names are specified with smtpd_restriction_classes in
main.cf. This adds 70 parameters to the "postconf" output,
more if additional mail delivery transports are defined in
master.cf. File: postconf/postconf.c.
This eliminates the long-standing problem of invisible Postfix
parameters. Fixing this (and adding support for pretty-printing
master.cf) took 500 lines of code, but the result was worth the
This is an isolated change; you can copy the postconf source
directory into any supported Postfix release and it should work.
