Forwarding email with usermin does not include 'sent from' email address

At the moment 'On 26/Mar/2009 15:26 Paul Lauria wrote ..' is generated when forwarding email.

It would be useful to be able to 'switch on' the following functionality:

'On 26/Mar/2009 15:26 Paul Lauria [paul@mydomain.com] wrote ..'

This means that the receiving email address has the originating email address.
