Modifying the content type of an attachment in a CDO.Message object
问题 When I try to add an MHTML file as an attachment to an email message in VBScript, the ContentMediaType is incorrectly set to "message/rfc822" (RFC 822). From what I understand, this is correct according to Microsoft, but is incorrect according to RFC 2557 which states that it should be "multipart/related" . This is a problem, because most (if not all) mail clients interpret "message/rfc822" as an email message. Since the file extensions ".mht" and ".mhtml" do not match any valid file
