No, not a request for insulation...
We've got exim feeding mail to an external binary which checks a
password file (check_local_user is disabled), quotas and delivers
mail somewhere if appropriate.
If the user doesn't exist then the binary has a return code of 128,
if the user is over quota then the return code is 192.
What we want is for exim treat the failure to deliver as it would
if check_local_user was enabled and the user didn't exist. i.e a bounce.
However the current behaviour seems to be that exim is sending a bounce
*and* freezing the message. I've read through the docs and as far as I can
tell unless temp_errors or ignore_status is set exim *should* treat the
above as a permenant error.
Here is an appropriate log extract:
root@scree:/var/log/exim4# fgrep 1ARpCO-0000Eg-2F mainlog

I feel I'm missing something quite fundamental here but my brain is feeling
rather scrambled.
Thanks
