Answer 1

You may be getting a Null Reference Exception when adding the "To" email address. You may need to initialize the "To" MailAddressCollection.

msg.To = new MailAddressCollection();
msg.To.Add(txtTo.Text.Trim());

aslo there is some useful info here on stackoverflow about sending SmtpClient.EnableSSL = true messages using certain ports.
