Isn't the best thing to do here to have a (system) filter option "archive"
which is pretty much like "save" except that:-

  1. It only archives a message once (not once per time through
     the filter).
  2. The out of band information is also saved - ie envelope
     and other info stashed by exim such as the invoking user.


An informational header could also be added at the same time (need a
add-header filter option maybe so it can be tailored).

This allows easy tailoring of
   1. what you save (arbitrary decisions based on
      to/from/subject/length/headers/encryption)
   2. where you save (mailboxes per user/subject/date etc)


Encryption/compression could be done in a transport but might be better to
stash stuff in straight files initially and then post process them daily.
Maybe you just put your mail archive store on WO storage.
