# Description

EmailValidator checks that a given String field, if not empty, is a valid email address.

The regular expression used to validate that the string is an email address is:

    \\b^['_a-z0-9-\\+](\\.['_a-z0-9-\\+])@[a-z0-9-](\\.[a-z0-9-])\\.([a-z]{2,6})$\\b

You can also specify expression, caseSensitive and trim params as a OGNL expression, see the example below.

# Parameters

- fieldName - The field name this validator is validating. Required if using Plain-Validator Syntax otherwise not required

Check also documentation of the RegexpValidator for more details - the EmailValidator bases on it.

Warning

Do not use ${regexExpression}, ${caseSensitiveExpression} and ${trimExpression} as an expression as this will turn into infinitive loop!
