Hello,
thanks for all the responses. According the the clamav ml
it happend to others as well and should not happen anymore if you're
using 0.93 of clamav*.

Similar hint came from Renaud Allard.
Thanks again.
We're selling this bug(?) now as feature: as exim stops transporting
mails in face of clamd failure, clamd fails scanning in face of missing
updates - always on the safe side for maximum security of our customers ;-)
