literal name_enable wherever possible, and ${name}_enable
when it's not, to prepare for the demise of set_rcvar().
In cases where I had to hand-edit unusual instances also
modify formatting slightly to be more uniform (and in
some cases, correct). This includes adding some $FreeBSD$
tags, and most importantly moving rcvar= to right after
name= so it's clear that one is derived from the other.
The program uses the postfix policy delegation protocol to control access to
the mail system before a message has been accepted (please visit
http://www.postfix.org/SMTPD_POLICY_README.html for more information). It
allows you to choose an action (e.g. reject, dunno) for a combination of
several smtp parameters (like sender and recipient address, size or the
client's TLS fingerprint).
