Why do you spend any time at all dealing with bounces from subscribers
who have gone unreachable?  See below for what should happen to them....

If that's what you're worried about then either you've adjusted the
wrong parameter, or I've assumed you've adjusted the wrong parameter.

If all the MXers are unreachable then the message is in your queue and
no DSN of any sort is sent anywhere until the five days has expired, at
which time your MLM software gets one single copy -- not you, but your
MLM.  If I'm not mistaken most modern MLM packages have the ability to
automatically unsubscribe or suspend any address that gets more than a
given number of bounces.  The human list manager should never even peek
at these messages unless a manual complaint is sent about someone being
unsubscribed accidentally.

Adjusting your own MTA's queue retry time limit will not defer one
single DSN that comes from any other queue.
