^[_a-z0-9-]+(/.[_a-z0-9-]+)*@[a-z0-9-]+(/.[a-z0-9-]+)*$
^(([0-9a-zA-Z]+)|([0-9a-zA-Z]+[_.0-9a-zA-Z-]*[0-9a-zA-Z]+))@([a-zA-Z0-9-]+[.])+([a-zA-Z]{2}|net|com|gov|mil|org|edu|int)$
^([a-z0-9A-Z]+[-|//.]?)+[a-z0-9A-Z]@([a-z0-9A-Z]+(-[a-z0-9A-Z]+)?//.)+[a-zA-Z]{2,}$
/w+([-+.]/w+)*@/w+([-.]/w+)*/./w+([-.]/w+)*
