Rolling your own email addressess validator is generally considered a bad idea. Just look at the 6.5k regexp written by Jeffrey Friedl (that is used in Email::Valid), or dig into the code of Abigail-II's RFC::RFC822::Address (which uses a different tecnique based on Parse::RecDescent).

Anyway, I don't have anything against reinventing wheels in order to learn. This leads to your question. Which I can't reply :) You just say that your RE fails when put into your cgi. It would be nice to know what is the string used in the matching, what was the desired output, and what was the actual output. And a small, but not smaller, piece of code that shows how your regex is used in its context.
