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. me@really.big.com). 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.

^([0-9a-zA-Z]+[-._+&amp;])*[0-9a-zA-Z]+@([-0-9a-zA-Z]+[.])+[a-zA-Z]{2,6}$
Description
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\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. user@domain.com), sub domains (e.g. user@foo.domain.com), the new two- and four-letter domains (e.g. user@domain.tv and user@domain.name) and country codes (e.g. user@foo.com.us). 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. user@domain.123), simply delete the last two occurrences of &quot;\d&quot;.
Matches
foo@foo.com | foo@foo-foo.com.au | foo@foo.foo.info
Non-Matches
foo@.com | foo@foo..com | foo@me@.com
