Ваш аргумент для адреса от не является действительным адресом электронной почты. 

client.Send("from",

От должен быть действительный адрес электронной почты.

В Sub btnSend_Click (около строки 84): 

client.Send("from", txtTo.Text, txtSubject.Text, txtMessage.Text)

"from", вероятно, должен быть правильно сформированным адресом электронной почты.
