I guess you're talking about the 13 useless crap lines at the end of your 
mail you've sent to a mailing list archived all over the world publically, 
but are required by the some change of laws in Germany.

Well, where some posts in this list about how to change / replace a part 
of the mail. MIMEDefang is using MIME::Tools for managing a mail, with in 
turn uses MIME::Head for managing the headers.
- From its man page:

$head = MIME::Head->new;
$head->replace('content-type', 'text/plain; charset=US-ASCII');
$head->replace('content-length', $len);

- From the mimedefang-filter man page:

action_rebuild()
Rebuild the mail body, even if mimedefang thinks no changes were made. 
Normally, mimedefang does not alter a message if no changes were made. 
action_rebuild may be used if you make changes to entities directly (by 
manipulating the MIME::Head, for example.) Unless you call action_rebuild, 
mimedefang will be unaware of the changes. Note that all the built-in 
action... routines which change a message implicitly call action_rebuild.

Note the phrase "(by manipulating the MIME::Head, for example.)" I haven't 
done something like that before, but you might find some examples in the 
archive - well if the "confidential information" signature doesn't prevent 
you from reading it ;-)

Maybe the sample filter 
http://whatever.frukt.org/mimedefangfilter.text.shtml helps you. They call 
lots of MIME-related functions.
I guess you'll get more samples by searching for "mimedefang 
action_rebuild".

Bye,
