Problem on sending emails

M

Mr. X.

Hello.
I have an asp.net, that sending emails.

I have the following code :
Dim mail As New MailMessage
Dim smtp As New SmtpClient("my-site.org")

smtp.Credentials = New NetworkCredential("(e-mail address removed)",
"myPassowrd")
mail.From = New MailAddress("(e-mail address removed)")
mail.To.Add("(e-mail address removed)")
mail.Subject = "Contact"
mail.Body = "<html> <body>...</body> </html>>
mail.IsBodyHtml = true
smtp.Send(mail)

Everything works fine, till some changes of the site provider.

Now I am getting the message :
The SMTP server requires a secure connection or the client was not
authenticated.
I have been told, I need to add some parameter : required authentication.
Why may be that change?

Thanks :)

Maybe checking the inner exception for more information would help:
