mail/postfix: install bin/{mailq,newaliases}?

[Edgar Fuß <ef%math.uni-bonn.de@localhost>]

I'm asking myself whether mail/postfix should be installing bin/mailq and bin/newaliases (which are symlinks to sbin/sendmail) on a system equipped with mailwrapper(8).

This has bitten me in three different ways:
1. On a system with pkgsrc postfix installed, but deliberately using postfix 
   from base (and mailer.conf set to base), calling mailq (with /usr/pkg/bin in 
   PATH before /usr/bin) called the wrong thing.
2. On a system with pkgsrc postfix installed, in use, but mailer.conf 
   mistakenly configured to base (and /usr/pkg/bin in PATH ahead of /usr/bin), 
   the mis-configuration was partly hidden because mailq called the pkgsrc 
   version.
3. On a build server with pkgsrc postfix installed, net/nagios-plugins 
   configures it check_mailq to call /usr/pkg/bin/mailq, which fails on 
   systems without pkgsrc postfix installed (while calling /usr/bin/mailq 
   would work regardless of postfix being installed or not).

Opinions? One could argue that:
1. occurs wherever a package shadows a program from base
2. is a level 8 problem
3. should be dealt with by teaching the configury to use /usr/bin/mailq if 
   present whenever /etc/mailer.conf exists or it's a link to 
   /usr/sbin/mailwrapper.
