If you read those threads closely, then you saw a whole bunch of "don't do this with a regular expression" type posts. There is a module on CPAN called Email::Valid which does a pretty good job. Also, since you know the nodes are out there and know how to specify the content you want, you might try using the handy "Search" box that crops up at the top of every page or, failing that, Super Search (look underneath the chatterbox for the link).

Let's try, at random, the following phrase match email address (follow that link and you'll get what you would have got had you typed that phrase into the search box).

HTH! (I hope I don't sound like I'm lecturing; I really am doing what I think will help you most on this question and in the future.)
