For Postfix, that requires routing the email through an external tool to
mutilate the content, then injecting it again.  On the plus side, you can
probably use a regexp header_match table to detect emails without the tag,
making life much easier for you when it comes to the routing decision.

...which, um, anything in particular?  Just in general?

I can't think of anything small.  Most of the tools that do this are
targeting something bigger, like injecting "disclaimers", or anti-spam
processing.

I would probably use something custom in Perl and MIME::Lite, which is only a
few dozen lines of code, but that is non-trivial work if you don't already
know how.  Python can almost certainly be turned to the same end.
