By default Sendmail will never bounce a bounce, a.k.a. a double bounce.  Rather Sendmail
will file it in the dead mail file.  I also believe that if Sendmail can not file dead
mail it will leave the message in the mail queue as a Q<queue id> file.  You can
configure Sendmail to forward double bounces on to a specific address if you want to.  In
fact I have done such to make sure that dead mail does not hang around in my mail queues. 
I just have the dead mail routed to /dev/null.

Milter ordering is indeed VERY important.

What is "it" that you will have to eventually deal with?  Where will you have to
deal with it?

What are you wanting / hoping that Sendmail will / would do / scrutinize?  Sendmail by
default wants to move mail.  As such, Sendmail will tend to move any mail that it can. 
Sendmail tends to be more like an ISP, a bit mover, or in this case a mail mover. 
Sendmail does not care what the mail is, or where it came from.
