There is a little known utility called look(1), (it does a binary
search on a sorted text file-so is very stingy with machine
resources-that came out in Unix 7,) and can be used with procmail(1):
    
    :0:
    * ? test -f "${HOME}/.procmail.file"
    * ? look -f some_word "${HOME}/.procmail.file"
    the_file

and if some_word, (like an e-mail address,) is in the
~/.procmail.file, then the e-mail will be filed in the_file, (or
whatever.)

~/.procmail.file can be very large without straining machine
resources.
