Description:

Mail::RFC822::Address validates email addresses against the grammar
described in RFC 822 using regular expressions. How to validate a user
supplied email address is a FAQ (see perlfaq9): the only sure way to
see if a supplied email address is genuine is to send an email to it
and see if the user recieves it. The one useful check that can be
performed on an address is to check that the email address is
syntactically valid. That is what this module does.

This module is functionally equivalent to RFC::RFC822::Address, but
uses regular expressions rather than the Parse::RecDescent parser.
This means that startup time is greatly reduced making it suitable for
use in transient scripts such as CGI scripts.
