I agree, but at least the copy I receive is very hard to read. It doesn't display as HTML, rather all HTML code shows up on the screen. The reason is likely that in the email header there is a blank line before
Content-type: text/html; charset=iso-8859-1
which needs to be part of the header without blank lines preceding it. There are also other header fields that appear after a blank line. Incomplete headers are likely to activate spam filters. Can this be fixed?
