That's not true for exim either.  It's a configurable option so that those
MTA's which refuse messages with more than X recipients (to avoid some spam)
can be catered for.  Exim can be configured with different limits for
different domains.

Nor for exim.  It's a configurable option.

Nor exim

I have a mailing list of thousands that clears those that are deliverable in
a minute or less.

On the other hand there's an exchange server on site that self destructs
whenever its users email a large-ish address book entry.
