I would make the secondary MX the primary and do all filtering there.
Then just make it forward all mails through the tunnel to your current
primary. This is easily done via a "relay" entry in the transports file
for your domain, like:     relay:[abcd::n]

Of course now you must make sure to have all valid mail addresses checked
already on the new primary (I use a map with all valid names in that domain).
