ok, in this followup, i'll try giving some useful advice:

don't stop doing this, but it will likely not work, at least, not quickly.

i think the default changed somewhere along the line but it was a long time
ago.

not lots, but definitely some.

i suggest "sort of" giving in. since it's an acl, you can blow a hole for
their mail server only. tell them that you're doing them a favor, and in X
months time, you're going to close the hole; that you're giving them some
latitude to change their non-compliant server over time.
