Note Submitter: gem@rellim.com ---- Another correction to the email pattern. Lot's of email addresses contain '+' chars. Listmanagers and whitelist spam blockers depend on this. The TLD (after the last period) is all letters, no numbers. No need to use a case insentive match then to match [a-zA-Z] when [a-z] will do. Underscore is not legal in domain names (RFC 1035) but still is commonly used, so I allow it. ANY char is legal in the username except [SPACE], =, or control chars (RFC 2821). Never seen < or > work though. So here is what I use, YMMV: eregi("^[!-;a-~]+@([0-9a-z][\w\-]+\.)+[a-z]{2,6}$", $email)
