REGEX for profanity

Does anyone know how to regex to block those fabulous 4 letter words that are proliferating? I tried just the word and it starts blocking a bunch of legitimate email.

TIA

You'd probably want to make sure there's whitespace on both sides of the word, otherwise you get matches on words that contain your expressions as substrings.
e.g.

How do I add white space in front of and behind the words?

The notation [:space:] will match whitespace, so

$ echo ' foot ' |grep foo

returns

foot

whereas

$ echo ' foot ' |grep '[:space:]foo[:space:]'

returns nothing.

O'Reilly's "Regular Expressions Pocket Reference" is handy to have around.
