You've probaly got MailMessage defined somewhere in scope.

try :
Dim message As New System.Net.Mail.MailMessage

There must be two namespaces where MailMessage exists.Check it.

Have a look on thread

you can use System.Web.Mail

Imports System.Web.Mail

Dim message As New MailMessage
SmtpMail.SmtpServer = "smtp.mail.yahoo.com"
message.[To] = "dhl_gandhi@yahoo.com"
message.From = "sender@domainName.com"
message.Subject = "Email Subject"
message.BodyFormat = MailFormat.Html
message.body = "Test Message"
SmtpMail.Send(message)
Response.Write("Email Sent")

Your server requires authentication. If you have an existing mail client connected to this server, try to look at the parameters of the connection to the smtp server, and try reproducing them in your mail client.
