Would it allay your security concern if you only accepted
HELO-with-domain-literal (a) from the known IPs of the
devices with the bogus SMTP implementation; and (b) if the
IP in the HELO statement is the same as the connecting IP?
(An alternative to messing about with your exim config
would be to implement a really simple proxy to convert the
bogus-SMTP into real-SMTP; I remember this being useful
with the wretched 3ware 3dmd thing which had a very
eccentric idea of what did and did not constitute a valid
SMTP dialogue.)
