Not sure I see what you are refering to above.  If you feel like
explaining any further, use the kind of language you would use to
address a 'simpleton'  : (

I did find some helpfull examples in nnmail.el, though that look like
something I breezed over in Info but didn't really catch on to.

I have noticed in many examples of mail splitting, the boxes are always
shown in this format 'mail.(dot)name' or 'mail.whatever'.

Lars points out that the actual word 'mail' isn't necessary, but is the
format 'word.word' required.  I just gave names to all mine in a single
word format like so:

(setq nnmail-split-methods
      '(("Box" "From:.*Joe Blow@redhat.com")
         ("Sea-Lore" "Sender:.*neptune@oceanic")
           ("mail.misc" ""))) Seems to work all right for some months
now.  But the stuff shown in nnmail.el is a different split method too.
The last one 'mail.misc', is probably more the result of copying heavily
rather than by design.

Looks like nnmail.el has an example that looks for all the world like it
splits on more than one line.  Unless this is just a joke on Lars for
always 'hawking' those little milk containers.

Understanding why this format does what it does was a little more than I
could absorb, must be making a second sweep or something on the matching.
