Default adding signature to outgoing mail // altermime/postfix/debian lenny

hello there, I configured a mail server using
http://www.howtoforge.com/virtual-us...l-debian-lenny

and that's all fine and dandy, however the client requires a signature to be automatically added to every outgoing mail so I found this
http://www.howtoforge.com/add-discla...ix-debian-etch

However I've got a little bit of a problem with it, I think it centres around the line
-o content_filter=dfilt:

Here's my master.cf

Code:
#
# Postfix master process configuration file.  For details on the format
# of the file, see the master(5) manual page (command: "man 5 master").
#
# Do not forget to execute "postfix reload" after editing this file.

if I unhash the line -o content_filter=dfilt: near the top then I get the error

fatal: /etc/postfix/master.cf: line 24: bad transport type: content_filter=dfilt:

in my logs, if I hash that out again and try putting it just below
127.0.0.1:10025 inet n - - - - smtpd, then the mail loops within the server and will eventually come back undelivered because of too many hops.

I discovered by accident that if I unhash the line near the bottom, send a mail and then revert to the correct config (without the dfilt) before the mail goes through too many hops, then the mail is delivered ok with the signature.

That suggests to me that the disclaimer script works but there's something up with the transport.

Can't figure out what though, any ideas?
