Possible result codes for the array items are: Item 0: [true|false] true for valid email address false for NON-valid email address Item 1: [SMTP Code] if a valid MX mail server found, then fill this array in with failed SMTP reply codes Item 2: [true|false] true for valid mail server found for host/domain false if no valid mail server found
Item 3: [MX server] if a valid MX host was found and connected to then fill in this item with the MX server hostname
