I didn't see any patch, I'm afraid.

Both at rcpt to: time :-)

Indeed. However, I'm not quite sure of the advantage of insisting on a
correct helo/ehlo at the moment it's given. Granted it would be "neater"
to give replies in sequence, but then you'd have to have a mail_from ACL
in addition, to keep it logical. As it is, there are 2 relevant ACLs,
rcpt and data (the others are irrelevant here.)
Believe me it's not my intention to denigrate, goodness knows. But one
could carry on producing refinements to Exim ad infinitum - as it is it
does a very good job with a lightweight daemon and, as far as I'm
concerned, does more and does that far better than any other MTA out
there.
Best,
Tony
