This probably means that deliver crashed. Maybe instead of executing
deliver directly, you could execute deliver.sh that works something
like:

#!/bin/sh

cd /tmp
ulimit -c unlimited
/opt/dovecot/libexec/dovecot/deliver $*
code=$?
if [ $code != 0 ]; then
  echo 'deliver failed' >> /tmp/deliver.err
fi
exit $code

Then see if deliver wrote a core file to /tmp or to user's home dir (if
user has one). If you do get a core file, get gdb backtrace:

gdb /opt/dovecot/libexec/dovecot/deliver core
bt full
