For SendMail, mailq is just a symlink to the SendMail executable.

the "mail.conf" stuff (to use a polite word) installs it's own executable(s)
under all the 'common' names that SendMail is invoked as.  These
executables look at /etc/mailer.conf, and invoke the appropiate executable
for the mailer that you have seleccted in mailer.conf.
