Since version 1.5.0p14 the subject and addresses of HTML emails were escaped, i.e. the characters '<', '>' and '&' were replaced by '&lt;', '&gt;' and '&amp;', if present. This resulted in a slightly more unreadable subject if any of these characters were present and if an email address contained an ampersand it would result in an invalid (escaped) email address.
