/*	Explanations:
		The regular expression does the following: it wants to scan the entire value from the beginning of the line (^) to its end ($):
			/^ [stuff] $/
		The address should start with a bunch of alphanumerical (letters or numbers), underscores, dots or dashes. This is the user name.
			([a-zA-Z0-9_\.\-])+
		Then comes an @.
			\@
		After that comes the domain name, which may include several sub-domains (mail.international.company.).
		Therefore we now allow several series of alphanumerical characters and dashes, followed by a dot.
			(([a-zA-Z0-9\-])+\.)+
		Finally the top level domain, once again we check for alphanumerical characters, but now without the dash
			([a-zA-Z])+		//original version ([a-zA-Z0-9])+
