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".
