Comment:
The original expression accepts adresses like ___@___.__ , this should work better: ^((?:(?:(?:[a-zA-Z0-9][\.\-\+\_]?)*)[a-zA-Z0-9])+)\@((?:(?:(?:[a-zA-Z0-9][\.\-\_]?){0,62})[a-zA-Z0-9])+)\.([a-zA-Z0-9]{2,6})$ But one problem remains: the max length of the Domainname is not correctly defined.
