There seems to be two cases when creating an HTML bodypart in a MIME
message.
Case 1: the user is composing the HTML directly in a WYSWYG mail client editor.
In this case all relative URLs could easly be expanded by the mail client to
the full URL.
Case 2: the user drags and drops an existing HTML page off of the Web or from
somewhere else. In this case the user wants the page to go "as is". For
the mail client to "fix up" the HTML page it runs the risk of breaking
something.
Better to leave the HTML page alone and on the receiving side set the base URL
in the browser just before the HTML page is displayed.

I think it should be "cid:222222" instead of "cid:<2222222>".
In RFC1630 the "mid:222222" is defined to be without the "<>". Unfortunately
its not very clear in RFC1630 about "cid:", but it should be consistent.
