Yes, it doesn't, and I think I know why. I have been hearing for years how
it just doesn't matter whether young people learn how to spell common
words, and I have steadfastly taken the position that it does matter.

It turns out that people who can't spell, and who leave school confident
that it is an out-of-date art, slowly discover all the odd places where
knowing how to spell actually makes a difference.

So, now that you are living in reality, perhaps you will discover one of the
problems with your regular expression is that "Recevied" isn't a word, and
it won't filter out those e-mails you want to collect.
