Warren is correct. The requirement is only that mail addressed to
<postmaster@domain> be accepted (and presumably delivered to _some_
account). There's no requirement that there be an actual postmaster
account; <postmaster> mail can be delivered to any account.

Sure, SIMS 'knows' about its routing table in the sense that it can parse
it and evaluate addresses with it. However, SIMS does not specifically keep
track of whether or not <postmaster> routes to a deliverable
address|account. IOW, SIMS does not 'know' from the routing table if it is
in compliance with the RFC requirement to accept mail for <postmaster>. It
probably could if it were programmed to do so. But, at this point, it
almost certainly never will since SIMS development has long since ceased.

Right, but as noted above, SIMS does not specifically keep track whether or
not there is routing for <postmaster>.

Not the end. Given that SIMS doesn't check whether or not <postmaster>
routes to a deliverable address|account, the simplest way for it to ensure
RFC compliance is to make sure that an account named 'postmaster' exists.
You can certainly choose to disable admin access for 'postmaster' and to
route <postmaster> to another account, but SIMS will insist that you have a
'postmaster' account.
