[MlMt] Spam complaints from MailMate?

[Seebs]

So, I am sorta old fashioned and actually try to complain about some of 
my spam.  To do this, in the past, I've been using formail to strip the 
last received header (note:  Before you point out that this is stupid, 
consider that I have a mail setup in which after mail is delivered to my 
mailbox, an extra header is added to it internally) and send a copy to 
some suitable mailbox.

So "forward" is nearly right, except that in Mailmate, that makes it 
into an uneditable attachment.  I don't want that; I want something sort 
of like a reply, except that I want absolutely completely full headers 
-- with the spurious last Received header removed since overworked abuse 
desks tend to misinterpret it.

Is this the sort of thing I can reasonably configure Mailmate to do?
