Attached html document automaticly opens in the body of the email I send from VB.Net page.

I send form information as a generated html attachment on an email, but when sending to clients using Lotus Notes (ver. 7.02) the attached html document is opened as part of the email body.

This does not happen in Outlook or Hotmail.

Now other, older ASP applications in the same environment send emails with HTML attachments by saving them on the server and then attaching them, so it might have something to do with the way the attachment is made with the StreamWriter, but I fail to see how that should affect the final result of the mail.

The HTML document has <!DOCTYPE html PUBLIC ""-//W3C//DTD XHTML 1.0 Transitional//EN"" ""http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd""> which I tried to change to HTML 4.0 to see if that made a difference, but it didn't.

I tried (as you will see in the code snippet) to send the body as plain text, hoping that it wouldn't attempt to blend them together, but to no avail.
Dim L_objEmailClient As New System.Net.Mail.MailMessage()
 

L_objEmailClient.Body = body.ToString()

L_objEmailClient.IsBodyHtml = False
 

Dim L_data As Byte() = Encoding.ASCII.GetBytes(attachment.ToString)

Dim L_MemoryStream As New System.IO.MemoryStream(L_data)
 

Dim L_StreamWriter As New System.IO.StreamWriter(L_MemoryStream)
 

Dim mail_Attachment As New System.Net.Mail.Attachment(L_MemoryStream, "registration.html", System.Net.Mime.MediaTypeNames.Text.Html)
 

L_objEmailClient.Attachments.Add(mail_Attachment)
 

smtpClient.Send(L_objEmailClient)

Lotus Notes always displays file attachments inline with the body of th email.  There are no other options.

Thats not true.
Usually it will stick the attachment icon somewhere in the body of the HTML, but here the problem is that it displays the HTML from the attached document inline with the mail content.

As I said several of the old ASP solutions manage to send emails to the notes clients with a html file attached with no such problems.
If I send these to myself and forward it to the client, the attachment shows up as an attachment, and not as content of the email body.

Apparently the change of headerinformation when it passes through my Outlook is sufficient to get Notes to handle it properly.

What I don't know if how to control that headerinformation to make Notes swallow it directly from the application.

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

I've never used System.Net.Mail.MailMessage, so I'm not sure what options are available, but the first thing I would try is to use MediaTypeNames.Application.Octet as the mime type.
