System.Net.Mail and Multiple .To() addresses

I'm still milling over if it's a step forward or a step back on this one. Or, if I'm just missing something on it.
Is there a way to specify multiple email addresses in the To line of a message created with the new mail Namespace.
With the old namespace, I could just use address1@dotnet.itags.org.mail.com; address2@dotnet.itags.org.mail.com; address3@dotnet.itags.org.mail.com
This worked great, since it allowed everyone that was in the To line tobe visible, and not require sending 15 emails to the SMTP server, justone, and then it created what it needed to send out to each recipient.Now, I get an error that the recipient email is malformed, and can'tsend it. Know of any way around this?
Dim Msg As New MailMessage
Dim To_Addr As MailAddressCollection = Msg.To
To_Addr.Add(New MailAddress("address1@.mail.com", "Some Person"))
To_Addr.Add(New MailAddress("address2@.mail.com", "Some Other Person"))
To_Addr.Add(New MailAddress("address3@.mail.com")

Muchas Gracias. I'm still trying to get the hang of all of the changes, and my last solution was from-the-hip as it was. Apparently, ASP.NET 2.0 is much less forgiving of from-the-hip programming...
Now, for whatever reason, I've come up against a new error...

Server Error in '/' Application.

The code behind this is is exactly as it shows up there. So, I'm backto confused... if I take out the "New" I get "Not set to Instance of anObject" errors.


I think you need to put () at the end of New Mailmessage()
From the SDK:
Usage

Visual Basic
Dim mailMessage1 As NewMailMessage()

According to Microsoft, the ";" separated [To] adress list string should work - see the SMTP send method at :

No, I get the same error, unfortunately.
