It also applies to pipes in .forward files, so if David has a
"|procmail" entry in his .forward, that will force sendmail to use the
prog mailer instead of local.  FEATURE(local_procmail) in your .mc is a
better solution, which will tell sendmail to use procmail as the local
delivery agent, so you don't need .forward at all.
