Email::EMAIL_MAX_LENGTH

Defines the max length for an email address

The maximum length of an email address is 254 characters. RFC 3696 specifies a total length of 320 characters, but mentions that addresses longer than 256 characters are not normally useful. Erratum 1690 was then released which corrected this value to 254 characters.
