I'm not so surprised about it because I've seen so many broken HELO on 
SMTP for twenty years.
But at least SMTPCONF=reject:nohelo is known practical because it is the
default of DeleGate for six years without a problem.

Restriction based on the MX record should not be done alone but it should
be used to activate other restriction like "callback".
Anyway, so far, my configuration SMTPCONF="callback" with
SMTPCONF="reject:pipeline" with SMTPGATE configuration is enough for me.
