Errormessage Comodo "MailScanner: MHTML files..."

Hi, I keep getting the message

=====
Our virus detector failed to completely analyse a message you sent:-
To: desktopantispam@spam.comodo.com
Subject: Spam Reporting to Comodo - User Selection
Date: Sun Dec 31 16:55:02 2006
Any parts of the message that could not be analysed will not have been delivered.

If you are using Microsoft Outlook, we strongly recommend you change your outgoing message format from “Rich Text” to “HTML” or “Plain Text”.

  1. Click on the “Tools” menu and choose “Options…”
  2. Got to the “Mail Format” tab
  3. For message format, select “HTML” or “Plain text”
  4. Click OK

The virus detector said this about the message:
Report: Report: MailScanner: MHTML files can be used in an attack against Eudora (372799222.mhtml)

Problem is, I am quite sure I have followed these steps, checked and double checked them. Still this errormessage keeps falling at my e-doormat.

Anyone recognize this and have a solution?

Thanks,
Ron C. de Weijze
-new to Comodo, after having gone the journey with BleuFrog. suppose this is a close relative.-
