Description

This is the regex for email validation in Struts:

\\b^['_a-z0-9-\\+]+(\\.['_a-z0-9-\\+]+)*@[a-z0-9-]+(\\.[a-z0-9-]+)\*
\.([a-z]{2}|aero|arpa|asia|biz|com|coop|edu|gov|info|int|jobs|mil|mobi|
museum|name|nato|net|org|pro|tel|travel|xxx)$\\b

This doesn't allow special characters (e.g. àéí, äëö,...).

However, International characters above U+007F are permitted by RFC 6531

Because some mail servers seem to follow this standard, regex should be improved to allow email addresses valid according to this standard.
