        smtp.Host = "smtp.gmail.com";
        smtp.Port = 587;
        smtp.Credentials = new System.Net.NetworkCredential("test1@gmail.com", "myPass");

You're not sending from the same email address you're authenticating with... You must add test1@gmail.com as the "from"

EDIT:As Bala R suggested, probably your firewall based on the error you get
