You could also check the permissions of /var/tmp and /tmp to make sure you
can write to the dir.

A while back I had to do an strace on the delivery exim process and found
that the DB routine tried to access the dir and couldn't, so it gave that
error and sent me on a wild goose chase for 2 months.
