Yes, it can be very useful. Set localhost_number to a unique value
on a group of exim servers. Then you can merge queues on machines
knowing that there's no chance that messages on one queue will
overwrite messages on another. This is useful when you want to take
down a server for an upgrade. You can just move the queue onto
another server.

Messages on qmail's queue have the same name as their inode number.
Inode numbers are unique, so this is a way of getting unique message
names. If you move qmail messages around, you're almost certain
to destroy the link between the message name and its inode number.
Which can be something of a disaster. You'll need to use something
like Eric Huss's queue-fix utility which can rename the message
files to match their inodes.

Blimey, I'm commenting on qmail and I've never used the software...I
must get a life...
