Ouch! Most of /var/spool/exim certainly doesn't belong on a tmpfs
filesystem ... an MTA is supposed to ensure that a message is securely
written to non-volatile storage before returning the final 'OK' in an
SMTP session. It's fine to have /var/spool/exim/db on tmpfs though ...
which is the hottest point of that hot directory.

Of course I'm somewhat prejudiced in this matter being an old-fashioned
mail administrator ... in reality modern systems are reliable enough
that you may choose to put /var/spool/exim on tmpfs and cope with the
risk of lost messages. 

Of course if you're really worried about how fast messages get into and
out of /var/spool/exim, then may I suggest something other than email
such as IM ?
