Miguel Almeida created WW-4395:
----------------------------------
Summary: Make email validator regex comply with RFC 6531
Key: WW-4395
URL: https://issues.apache.org/jira/browse/WW-4395
Project: Struts 2
Issue Type: Improvement
Components: Core Actions
Affects Versions: 2.3.16.3
Reporter: Miguel Almeida
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 [1]
Because some mail servers seem to follow this standard, regex should be
improved to allow email addresses valid according to this standard.
