HTML unipart mails


I recently noticed that mail produced with Microsoft’s
e-mail-client (which produces unipart html messages) do get correctly
converted to text by rt (as of 3.4) but the mail module does not seem to
get the converted data.

Instead, the outgouing mail from rt says:

This transaction appears to have no content

This is most likely because there was no text content, but only
text/html content.

Is this a configuration issue or a bug?
