Sendmail was pretty much all fixed by the time postfix was released,
and made even better with the addition of the milter interface that
lets you run scanning, etc. processes under different uids but able to
participate in the smtp conversation. Postfix eventually got around
to copying that too.

Just another change for change's sake as far as I'm concerned.
Sendmail continues to work just fine and the configs as shipped rarely
take more than a few lines of change in the m4 file to do normal
operations.

It's not postfix doing that, it is you, doing whatever has to be done
to keep your lists in sync. Still, I don't see the point of even
having a secondary MX. The days are long gone when chunks of the
internet can't reach each other for long periods of time and anything
sending should do its own queuing and retries. In fact if you do
greylisting, you have forced all of your senders to prove it.
