You can do that with a Header ALL rule; it will work more reliably as a 
local rule because you know how your local MTA is annotating the envelope 
recipient address in the headers, where a rule provided as part of the 
base set would be hit-or-miss and hugely complex and would better be done 
in a plugin.

Indeed. Markus must not get much email.

If you do develop such a rule for metas, be very careful how you use it.
