E-mail (Validation)
Description	The E-mail (Validation) identification analysis definition identifies whether or not an e-mail address is syntactically correct.
Examples	Input	Output
	VIRGINIE.MAZOUINGMAIL.COM	INVALID
	WBARBER@EARTHLINK.NCT	INVALID
	wrobinson@helixtechnology	INVALID
	Ajari@evolvingedge.net	VALID
	al@crestnational.com	VALID
	ALIEMARATI@YAHOO.COM	VALID
Remarks	This definition performs a simple validation of the syntax of the e-mail input. It is not meant to be 100% correct according to international standards, but it is a practical approach to screen your e-mail addresses. Addresses with embedded comments are recognized as invalid, even though the address may be correct. Certain rarely-occurring but otherwise valid constructions (such as valid control characters in a quoted mailbox) are recognized as invalid. Certain rarely-occurring but otherwise invalid constructions (such as double-hyphens in a sub-domain name) are recognized as valid.
