I hadn't thought of that, but people who are dealing with highly
technical e-mails would probably also be able to customize their
local.cf file to effectively turn off the rule.

All my clients are professional agencies, and I don't think this really
applies to them.

I don't mind these getting blocked.  In fact, I'd love it if every time
someone sent me a very poorly written e-mail they got a bounce message
back telling them to turn on the spell check option in their e-mail
program.

True.  I hadn't thought of your book text example.

For me, this is less of a concern...my e-mail is a quad 3.2ghz machine
with 4GB of RAM, and it runs at about 2% processor usage most of the
time.  :)

As for whether or not a lot of SPAM has mispelled words in it or not:
every single e-mail that came to my inbox this morning that was SPAM but
wasn't tagged as SPAM were pure gibberish, and they would have been
caught by my proposed filter.  :)

So, while I agree that this filter wouldn't suit everyone, it would
certainly be a nice option to have.
