I thought space separated values would work so I have had this running 
for a while - but after a closer examination just now I've just realised 
that space separated is accepted without error but -doesn't- actually work.

In other words, the latest define of mail_replica silently overwrites 
the previous definitions.  This is probably desirable as it allows 
per-user settings to override global ones, however it means that yes, 
there appears to be no way to configure multiple mail_replica values and 
have them work...
