If you VERP, so you have one piece of email per subscriber per
message, you stop trying to outguess the MTA, since it can look at
everything and decide a delivery strategy (although even then, you
can affect the MTA by what order you submit messages). When you start
chunking things together, you start limiting the MTA's ability to
optimize, so you have to get smarter.
Sorting by domain is better than no sorting, but sorting by MX is
preferable -- but non-trivial and time-expensive. You basically get
back into becoming an MTA again, so it's probably better to go with a
domain sort and VERP, and just make sure you're configured to feed
the MTA fast enough to keep it busy without overloading it.
