Hello,
it seems to be known from the source code that exim sometimes
causes segmentation faults in the db-library (that are caught
by signal handlers in more recent versions).
I don't know if anybody is keen on some dumps, but we have some
of these segmentation-faults:
In this case, Exim tries to deliver a message to a mail-server at
194.221.80.15 that denies the reception by
"452 Not enough space in users account (0 bytes available)"
In rough, this is how everything looks with -v set:
hostie:/usr/local/lib/exim/lists # smail -v -M 0xMC8q-0003ej-00
delivering message 0xMC8q-0003ej-00

Any ideas where to look for the error? I might help with additional
testings or modifications.
I don't feel deep enough in the source to try finding out the
error by myself.
Greetings,
Georg
