Yes, I understood that as it also displays OK for me.  As I said, it is the mail message format that is wrong, not the HTML web display.

Is following related to http://community.pmail.com/forums/thread/19533.aspx?:
re html-only WSN msg 30/9/09 (file WSN_doctord.CNM, within WSN_doctord.zip attached) using WinPmail 4.41:  bits at beginning and end and at ends of lines/paragrs don't display.  Similar when you instruct "Open message in web browser" (Firefox);  in source file display in Firefox I could see some of the html was missing.
!! EASY REMEDY:  COPY WSN_doctord.CNM to WSN_doctord.htm, load latter into firefox, or IE.

Maybe - your message has overlength lines so has an invalid format.  The max length is 998 characters.

The HTML looks fine, so should display OK in a browser.

Thanks, PaulW.  I should have been more explicit:   WSN_doctord.htm did indeed display OK in Firefox.
