Title	Test Details Email - Overly Simple
Expression	^\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,3}$
Description	Simple email expression. Doesn't allow numbers in the domain name and doesn't allow for top level domains that are less than 2 or more than 3 letters (which is fine until they allow more). Doesn't handle multiple "." in the domain ([email protected]).

Title	Test Details Pattern Title
Expression	^[\w-\.]+@([\w-]+\.)+[\w-]{2,4}$
Description	This expression matches email addresses, and checks that they are of the proper form. It checks to ensure the top level domain is between 2 and 4 characters long, but does not check the specific domain against a list (especially since there are so many of them now).

Title	Test Details Pattern Title
Expression	^[\w\.=-]+@[\w\.-]+\.[\w]{2,3}$
Description	Much simpler email expression. This one forces a length of 2 or 3, which fits current specs, but you may need to alter the end as this one allows all numerals on the .COM section.

Title	Test Details Pattern Title
Expression	^([\w\d\-\.]+)@{1}(([\w\d\-]{1,67})|([\w\d\-]+\.[\w\d\-]{1,67}))\.(([a-zA-Z\d]{2,4})(\.[a-zA-Z\d]{2})?)$
Description	This pattern allows standard e-mail addresses (e.g. [email protected]), sub domains (e.g. [email protected]), the new two- and four-letter domains (e.g. [email protected] and [email protected]) and country codes (e.g. [email protected]). Also, this patter follows the Network Solutions standard length of 67 characters for top-level domains. The reason I allow numbers to be entered in the domain suffix is for future planning. If you do not want numbers to be able to be added as a domain suffix (e.g. [email protected]), simply delete the last two occurrences of "\d".

Title	Test Details Pattern Title
Expression	^.+@[^\.].*\.[a-z]{2,}$
Description	Most email validation regexps are outdated and ignore the fact that domain names can contain any foreign character these days, as well as the fact that anything before @ is acceptable. The only roman alphabet restriction is in the TLD, which for a long time has been more than 2 or 3 chars (.museum, .aero, .info). The only dot restriction is that . cannot be placed directly after @. This pattern captures any valid, reallife email adress.

Title	Test Details Pattern Title
Expression	^[\w-]+(?:\.[\w-]+)*@(?:[\w-]+\.)+[a-zA-Z]{2,7}$
Description	Matches 99.99% of e-mail addresses (excludes IP e-mails, which are rarely used). The {2,7} at the end leaves space for top level domains as short as .ca but leaves room for new ones like .museum, etc. The ?: notation is a perl non-capturing notation, and can be removed safely for non-perl-compatible languages. See also email.

Description	Matches a valid email address including ip's which are rarely used. Allows for a-z0-9_.- in the username, but not ending in a full stop i.e [email protected] is invalid and a-z0-9- as the optional sub domain(s) with domain name and a 2-7 char (a-z) tld allowing for short tld's like ca and new ones like museum.

Description	Email address validator. Should cover most of RFC 822, including unusual (but still valid) addresses. Does not restrict the top level domain size, but you're better off doing an nslookup or similar if you absolutely must have a valid domain. Accepts IP Addresses instead of the domain, with or without brackets. Believe it or not, this one is valid: !#$%^&*-+~/'`|{}@xyz.com Sorry looks like this site is mangling the quote and ampersand characters - you'll have to fix that yourself.
