Check the syntax on maxLength. It should be camel cased. Because you used all lower case, it cannot find the correct method.

You wrote:

'rule' => array('maxlength', 25),

It should be

'rule' => array('maxLength', 25),

See: http://book.cakephp.org/2.0/en/models/data-validation.html#Validation::maxLength

Also, you are writing the rule with a custom name like this:

'address' => array(
    'maxLength' => array(
        'rule' => array('maxLength', 255),
        'message' => "Your email address can't contain more than %d characters.",
        'on' => 'update',
    ),
),

Try changing it to:

'address' => array(
    'rule' => array('maxLength', 255),
    'message' => "Your email address can't contain more than %d characters.",
    'on' => 'update',
),
