I have not had to mess with mailto links much. However I now need to add a link in the body of a mailto if it is possible.
Is there a way to add a link or to change the email opened to an html email vs a text email?
<a href="mailto:firstname.lastname@example.org?body=The message's first paragraph.%0A%0aSecond paragraph.%0A%0AThird Paragraph.%0A%0ALink goes here">Link text goes here</a>
Section 2 of RFC 2368 says that the
body field is supposed to be in
text/plain format, so you can't do HTML.
However even if you use plain text it's possible that some modern mail clients would render the resulting link as a clickable link anyway, though.
