What you really want with sendmail is a milter-multiplexer like 
MimeDefang where you can do anything you want without slowing down the 
faster native sendmail steps and handle the unusual configuration parts 
in a snipped of perl.  Now that postfix has gotten milters right I think 
you could use MimeDefang with it too.

But, sendmail these days is probably the most strictly audited piece of 
code on your server so I think the OP is just following bad advice.
