Mail.app and Thunderbird seem to insert a space character before each added line break. Outlook replaces new lines in the email with double \n''s, then uses single \n''s for the ''soft'' line breaks.

Can this be done?
What I want: I get a normal http request containing a URL from a remote server. Instead of redirecting to that URL, I want to load it into an iframe on an existing page. I''ve tried a number of approaches with no success. Can anybody suggest a good way to do this?
