I have had

(insert-file "/etc/rc.conf.d/postfix"):

postfix_command="/usr/pkg/sbin/${name}"

for a long time on several systems, and been running pkgsrc postfix just
fine.


The load_rc_config at the end overrides the standard variable settings.

I don't think it's necessary to set start/stop/reload as the normal
/etc/rc.d/postfix sets them to

start_cmd="postfix_op"
stop_cmd="postfix_op"
reload_cmd="postfix_op"

and

postfix_op()
{
	${postfix_command} ${rc_arg}
}

Probably one should set

required_files="/usr/pkg/etc/${name}/main.cf"

but I've never had trouble since the original is from the distribution
and I have a config file in pkgsrc.
