[Mimedefang] Server load

[Karel.DeBruyne at ua.ac.be]

All these messages about server load, but nobody tells us what else these
servers do.

My server is a Sun E450 with dual processors and 1GB RAM
At times this machine has got a very high load (4-8)
This machine is processing about 20k of mails/day.

But this server is our imap/pop server too...
