Thanks for the reply Mark. I checked the bounce settings and the
bounce_score_threshold is set to 5 and bounce warnings set to 0.

I checked the log file and the 2 e-mail addresses that this issue occurred
with are both non-existing e-mail accounts according to the exim_mainlog

See that is the mystery.

I will look at those and see if I can dig up anything.

Thanks again.
