[CentOS] postfix and upstart

Postfix on CentOS-6.2 evidently does not use upstart style
configurations. The author evidently has no plans on altering
Postfix's structure to accommodate upstart any time soon, if ever
Thus Postfix starts and stops using a sysvinit style script.

Nonetheless, I have an upstart configuration that I wish to be
dependent upon Postfix start and stop events.  Is anyone here aware of
some straight forward way of accomplishing this?

I am considering placing initctl emit statements into the sPostfix
script. Before I go down that rabbit hole I would like to know if
there is any other way provided by CentOS handling startup and
shutdown dependencies between the two forms of scripts.
