Problem sending emails.

[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("",
"myPassowrd")
mail.From = New MailAddress("")
mail.To.Add("")
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

***canned wrong-newsgroup reply************************ There was no way for you to know it (except maybe by browsing through some of the previous questions in this newsgroup before posting yours - always a recommended practice) , but this is a classic (COM-based) asp newsgroup. ASP.Net bears very little resemblance to classic ASP so, while you may be lucky enough to find a dotnet-knowledgeable person here who can answer your question, you can eliminate the luck factor by posting your question to a group where those dotnet-knowledgeable people hang out. I suggest microsoft.public.dotnet.framework.aspnet or the forums at www.asp.net.

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

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

"Why?"
Well, it sounds as if the site administrator wanted to make the site more secure. Maybe he was having problems with bots using his site to send spam or something.

Did you mean to ask how to make the change?
