Jmail - Attachment bliver til skodkode i mail

Hej Experter,

Jeg har lavet et lille system som skal sende en mail ud med er vedhæftet fil.

men mailen jeg modtager ser ret mærkelig ud.

koden til at udsende min mail ser således ud:

    Set mailer = Server.CreateObject("JMail.Message")
            mailer.From = "xxxx"
            mailer.FromName = navn
            mailer.AddRecipient "xxxx"
            mailer.Subject = "Formular: Lærling"
            mailer.Priority = 3
            mailer.Body = message
           
            ' Attach file hvis der er en.
            if len(filename) > 0 then
                mailer.AddAttachment("d:/inetpub/wwwroot/XXX/Files/Attachments/"& filename)
            end if
           
            mailer.contenttype = "text/plain"
            mailer.Send(serverIP)

det jeg modtager i min inbox ser således ud.

This is a multipart message in MIME format.
