You can kind of do this already by creating a text file, say
alphanum.txt, containing the characters a-z (and 0-9) on
separate lines. Then set up a filter "<Subject> NOT
Includes '$alphanum.txt'".

A work-around for this is to create a .txt file containing
the alphabet with one letter to each line. If you name this
file "alphabet.txt" then you can check to see if the
subject "Not Includes" $alphabet.txt
There is a more general point in your surgestion however:
It would be nice to have "Not Includes RegExp"

Just found this which seems to work:
<Subject> Includes RegExp '^\s{0,}$'

please disregard my last comment - "\s" isn't recognised so
it doesn't work :(
Feature Request: a more fully impemented "RegEx"
