MIME with "inline" attachment - problem when converting to Notes Rich Text

Hi

User configuration:

Format preference for incoming mail: Prefers Notes Rich Text

Tested Domino: 8.0.2 FP1, 8.5.1 FP3

When incoming mail contain inline attachment in MIME message:

Content-Disposition: inline

…this attachment is deleted from mail by router when converting to Rich Text

Any solution is Mime_Convert_Html_to_Attachment=1, but it is stupid solution - mail is empty and contain c.htm attachment - it is very uncomfortable.

MIMEForceAttachments - not working
