This is the code I use to send an email from an asp.net page:
Dim message As New MailMessage()
message.IsBodyHtml = False
message.From = New MailAddress("foo@foo.com")
message.To.Add(New MailAddress("foo@foo.com"))
message.Subject = ("Response from form")
message.Body = ("Email message here")
Dim client As New SmtpClient()
client.Host = "email.foo.foo"
client.Send(message)
