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Most email validation regexps are outdated and ignore the fact that domain names can contain any foreign character these days, as well as the fact that anything before @ is acceptable.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.

Expression
^([0-9a-zA-Z]+[-._+&amp;])*[0-9a-zA-Z]+@([-0-9a-zA-Z]+[.])+[a-zA-Z]{2,6}$

A short and sweet email address validator. Checks that the username starts and ends with an alphanumeric character, allows a few non-repeating 'special characters' (namely -, ., _, +, &amp;) and checks for a sensible domain name (2-6 character TLD required). Some unconventional, yet technically valid, addresses will not be matched, but this is only a simple expression ;-)

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
regex to validate email address noteworthy: (1) It allows usernames with 1 or 2 alphanum characters, or 3+ chars can have -._ in the middle. username may NOT start/end with -._ or any other non alphanumeric character. (2) It allows heirarchical domain names (e.g. [email protected]). Similar -._ placement rules there. (3) It allows 2-9 character alphabetic-only TLDs (that oughta cover museum and adnauseum :&gt;). (4) No IP email addresses though -- I wouldn't Want to accept that kind of address.
