Outlook voting buttons - MailMessage class

Hi,

Does anyone know if it's possible to add a custom header to the MailMessage class in vb.net for voting buttons?

I was able to add a custom header for "Reply-to", and send the email, but I need to know if it's possible for vb.net.

Should I be using other classes or components for this?
Here is sample code....

code Code:

Imports System.Web.Mail
 
Module Module1
 
    Sub Main()
 
        Dim message As New MailMessage
        message.To = "[email protected]"
        message.From = "[email protected]"
        message.Subject = "test"
        message.Body = "test"
        message.Headers.Add("?", "?") 'what goes here?
 
        Dim email As SmtpMail
        email.SmtpServer = "mail.bubba.com"
 
        email.Send(message)
 
    End Sub
 
End Module

Well, I got close, but then I could not find a way to convert an outlook.mailitem into a mailmessage item, so I can try to change the "from"

Here is how you do it in vb.net using redemption tool to avoid the outlook security thingy...

vb Code:

Imports Microsoft.Office.Interop
Imports System.Web.Mail
 
Module Module1
 
    Sub Main()
 
        Dim olApp As Outlook.Application
        olApp = CreateObject("Outlook.Application")
        Dim safeItem As New Redemption.SafeMailItem
        Dim olItem As Outlook.MailItem
        olItem = olApp.CreateItem(Outlook.OlItemType.olMailItem)
        With olItem
            .To = "[email protected]"
            .Subject = "vote test"
            .Body = "test message"
            .VotingOptions = "Yes;No"
        End With
        safeItem.Item = olItem
        safeItem.Send()
 
        olItem = Nothing
        olApp = Nothing
  
    End Sub

The only problem with this code is that you need to have an Outlook profile on the machine that is sending the email, and you cannot change the "from" address. :-(
