[Exim] too large messages don't get logged

hello,

Recently I saw that exim doesn't log messages rejected
because of their size if the sender supports ESMTP and tells
the message's size at the end of the MAIL FROM command. Is
it a misconfiguration on my part (I use loglevel 4 to avoid
lots of 'retry time not reached' in the mainlog), an exim
bug, or is it intentional? I looked into the source and
couldn't find logging statements in the specific part of
smtp_in.c.

greetings
endre
