i regularly configure ISP's with a limit on the size of email messages.
(generally 10meg, although i think 100k is probably better).

when they get a complaint, i then point them to the fact that many of the
large email messages get stuck in the queue because the receiving side
is too slow or doesn't have enough disk, or the users quota is full.

and of course, the sending user hears that it wasn't received, and then
assumes it was lost and resends it.

file transfer by email is evil.

i've been saying that for literally 10 years now:
