All paragraphs received okay here at my end.
My 2007 "outlook" email messages are not set for any margin width.
In my experience texts typed in some word processing programs and then
pasted into an email message will not wrap right margins well, even with
ragged right columns, because the last character space of a full long line
falls outside the column margin. In my new version of MS Word it falls
inside. The outside space causes soft returns to become fixed and hard in
email messages, so that you get lines as new paragraphs with only one word
in them. This of course may not be the cause of your present problem.
