^(?(")(".+?(?<!\\)"@)|(([0-9a-z]((\.(?!\.))|[-!#\$%&'\*\+/=\?\^`{}|~\w])*)(?<=[0-9a-z])@))(?([)([(\d{1,3}.){3}\d{1,3}])|(([0-9a-z][-0-9a-z]*[0-9a-z]*.)+[a-z0-9][-a-z0-9]{0,22}[a-z0-9]))$
Refer this page for more info on this regex:
[login to view URL]
test_@[login to view URL] is considered invalid. This pattern needs to be added without breaking existing valid email recognizitions.
