May I clarify?  So Dovecot MTA might be for inbound SMTP only?  Or 
also for outbound SMTP? (From the feature list I'd assumed outbound, 
as well.)

If also for outbound, we have thought to run inbound and outbound on 
different servers, with the outbound server not listening to any 
internet-capable ports, simply to reduce further the opportunity for 
external access leading to spam generation (because any inbound access 
could lead to privilege escalation due to some exploit, and alter the 
ACLs, for example).

Running on separate servers would imply standalone (unless config data 
is on NFS, perhaps).

Very supportive for the ideas listed, especially around email 
authentication, and security.
