Trapping all the email in postfix and using a bcc would either push the 
bcc'd email to another mail handler of back into cyrus in some other 
Which is doable but just seems clunky.

This could be the answer. I tried using always_bcc for another use and 
found that it had some quirks with cyrus so I have avoided it since then 
but it may be worth a revisit.

True enough but an always_bcc into the Sent folder would solve that problem.
