Do away with the obsolete text(1) -a operator, use sh && instead.
Prefer sh ! operator over test's ! (less question what it means).
A few minor formatting changes.

little bit verbose for slow machines

Handle variable expansion and comma/space separators in postconf.

From Timo Buhrmester:
https://mail-index.netbsd.org/tech-userlevel/2016/08/20/msg010301.html

Implement "status" command for postfix - makes tools like ansible
happier.

un-uppercase pseudodependency for the moment so as not to break pkgsrc

Add some magic (similar to the one in rc.d/sendmail introduced with 2.0
release) to not start postfix if $postfix is not explicitely set and

Add some magic (similar to the one in rc.d/sendmail introduced with 2.0
release) to not start postfix if $postfix is not explicitely set and
another mailer is selected in /etc/mailer.conf. Also print a warning if it
happens because the mailer in rc.conf is the removed sendmail.

This prevents starting two MTAs at once if one uses a custom MTA.

As proposed on tech-userlevel, approved by martin.

make postconf configurable

- find the correct newaliases program from postconf
(suggested by Geert Hendrickx)
- only check for hash files.

Find the alias file name from the postfix configuration. From our anonymous
user.

PR/33760: dieter roelants: a default install can't send mail due to
missing aliases.db

Add an _rc_subr_loaded variable, set to ":" by rc.subr. Scripts can use this
for a speedup by doing:
$_rc_subr_loaded . /etc/rc.subr

Store the full path to the /usr/sbin/postfix in $postfix_command
and use the latter postfix_op() to implement start/stop/reload.
(We generally use full paths in rc.d scripts.) Problem noted by Bill

Implement start_cmd as:
start_cmd="${name} "'${rc_arg}'
and stop_cmd & reload_cmd as:
stop_cmd=$start_cmd
reload_cmd=$start_cmd
(Just to be tricky)

populate /var/spool/postfix/etc with /etc/{localtime,resolv.conf,services}.
per suggestion from perry.

- only perform the checkyesno on the variable named in $rcvar (rather than
implicitly using $name if $rcvar isn't set), and always perform this check,
even when using start_cmd (et al).

- only perform the checkyesno on the variable named in $rcvar (rather than
implicitly using $name if $rcvar isn't set), and always perform this check,
even when using start_cmd (et al).
this check is performed before the pidcmd
is run, speeding up scripts that weren't going to be run anyway.
this should speed up booting slow systems.

- take advantage of the above and remove
start_precmd="checkyesno foo"
in scripts that use start_cmd.

- explicitly set rcvar=foo in the rc.d/foo scripts which have an equivalent
rc.conf entry

- fix `rcvar' and `restart' when $rcvar isn't set.
these above changes fix PR [bin/11027].

- when doing `force*', ignore the return value of *_precmd.
this fixes PR [bin/10781].

- rename what sysdb provides from `databases' to `sysdb', to reflect
the name of the script.

- improve the comments in rc.subr

You need to add a xxx_precmd with a checkyesno yyy if you use a xxx_cmd
in an rc.d script.

Provide rc.d support for the Postfix mail system. Committed to the
base because there is no support for packages in rc.d, and Postfix
is supposed to become part of the base system anyhow.
