Embedded Mime elements
In your Lotus Notes Client, go to "File", "Preferences", "Basic Notes Client Configuration".
The are two points "Show in-Line MIME images as attachments", and "Disable embedded brower for MIME mail". Tick both.
Now open the offending E-Mail and delete it.
Notes can normally deal with badly formatted E-Mails, on the odd occasion that a mail is extremely badly formatted, just do the above.
Update your Notes client to the latest licensed version you posess, and switch the mime setting back on, if needed make a mail rule moving or deleting the offending sender.
Sincerely
