We can't really help you if you are using incorrect user and password.

One thing: consider using:

smtp.Connect("webmail.dataglove-us.com");  // no port => default 587

-or-

smtp.ConnectSSL("webmail.dataglove-us.com"); // for SSL/TLS

Consider contacting your server administrator for authentication details.

If you get “The remote certificate is invalid according to the validation procedure” exception while trying to establish SSL/TLS connection, most likely your server certificate is self-signed or you are using incorrect host name to connect:

You can always accept invalid certificate (bad thing to do) using this code:
client.ServerCertificateValidate += (sender, args) => args.IsValid = true;
