PCRE + forany?
Magnus Holmgren has this wonderful construct for looking up all the IP
addresses in received headers .. perhaps it could be modified? It
doesn't use forany.

It doesn't seem to use forany .. and I really have no idea how to use it
:P Now that I offload things to a program listening on a socket, I've
become really lazy.
condition = ${if forany{\n, $h_Received:}{match{$item}{PowerMTA/i}}}
No idea if that works .. at all.
