Whose filter? Yours? If so, why not fix it?

There is no mail.gmail.com; are you faking DNS for a domain not under
your administrative control? If so, why?

You can pass data from the Routers down to the Transport by setting
address_data on the Router; this is then available in $address_data in
the Transport.
You could then have the file contain:
master-key: key1=foo key2=bar
and put the result of the master-key lookup in address_data and use
${extract...} to collect data from $address_data in the transport, eg
port = ${extract{port}{$address_data}{$value}{25}}
Then if you choose to add port=2525 to one of the lines, and only if you
choose to do so, you can deliver to a non-standard port.
But why are you faking up handling for Gmail traffic?
