This issue has recently been fixed in FLOW3 (after some discussion) [1].
Maybe someone feels like backporting this - unfortunately it is a 
breaking change though..

Probably the easiest solution for now would be to create a 
EmailOrEmptyValidator like:

class Tx_YourExt_Validation_EmailAddressOrEmptyValidator extends 
Tx_Extbase_Validation_Validator_EmailAddressValidator {
	public function isValid($value) {
		if ($value === NULL || $value === '') {
			return TRUE;
		return parent::isValid($value);


But, obviously this should be possible without custom validators too.
