Exim, Cyrus, Mutt + what?

[steve downes <steve@kingswayelec.co.uk>]

I am using debian testing with:-

Exim 3.36
Cyrus 1.5
Mutt 1.5.5

Very happy with it but want to add an auto mail sort to pre sort
mailing lists out from work mail into other boxes to read at my
leisure. Also a bit of spam sorting would not go amiss.

The choices I have been looking at are

Cyrus 2.1 (poor documentation, looks complex to set up & no idea how
      well it works)
Procmail (looks good but cannot see how to integrate it into cyrus)

But the documentation I find insufficient to get a clear picture of
what is possible. Any thoughts, pointers, or comments gratefully
received.
