[MlMt] Compound "is in" rule ... ?

[Robert Wall]

I basically want to write a rule that says:

if (
  (subject) is in folder “target” AND
  (from) is in folder “target” AND
  (subject) and (from) are from the same message
) then (
  file (message) in folder “filecabinet”
)

So if these two messages are in “target”:

From: Bill Jones	
Subject: Important Information Regarding Your Account

From: Dave Smith	
Subject: Your Receipt For Your Recent Transaction

and I get another message that matches one of them dead-on:

From: Bill Jones	
Subject: Important Information Regarding Your Account

I want it filed, but a message with a mixed match of subject/from:

From: Dave Smith
Subject: Important Information Regarding Your Account

shouldn’t automatically be filed, because the matched subject isn’t from the correct sender.

I’m guessing this isn’t possible, but I wanted to see if anybody has any brilliant ideas. :)
