This is a matter for demon.service ... pretty unlikely to be an
engineering priority I'd have said -- especially since almost everyone
now uses POP3 (where you do size control another way)

but what do I know ?  see .sig

that's clearly a good idea in general, but of course it won't change the
SMTP delivery code (which won't have any logic for honouring size limits
anyway)

are you saying that there isn't a DSN, or that the message attached to
the 5xx is not relayed ?
