our user based is split over 6 backends:

+----------+-----------------+
| mailhost | count(mailhost) |
+----------+-----------------+
| mail1    |           20857 |
| mail2    |            5655 |
| mail3    |            3237 |
| mail4    |           20926 |
| mail5    |            5645 |
| mail6    |            3296 |
+----------+-----------------+

You can see that mail1 and mail4 are have a lot more user, but these 
users are students that have smaller mailboxes.

The other hosts are primarily for staff.  e.g. mail3 reaches 1000 
concurrent users every day.  mail6 nearly reaches 1000.  I can't give 
you any figures of email received at the moment.
