ACK. But the (potential) bug and the 'defer' and log messages are
separate issues.
Please see if you can dig out a copy of the message that triggered that
and send it to me directly - offending headers unaltered, of course.
It 'should' give you an in-session rejection, AND NOT cause a failure
here (Exim 4.73, modified source, on OpenBSD 4.9 AMD-64, Exim ).
Either way, I'll check logs and let you know what was seen.
