I would like to ditto this. In a shared hosting environment where we setup the domains from various hosting platforms, then use the API (don't get me started on that...) We can easily have 500 domains, and with 1 postmaster/admin account per domain, that is a MASSIVE waste of accounts that count toward totals.
If there was logic to make sure a postmaster/domainadmin (for us postmaster is used) did not count toward these totals, that would allow us to allocate financial resources elsewhere.
I realize for companies that use a single SM install for only a few domains, this may seem unnecessary, but, in a shared hosting environment where there are hundreds to thousands of domains, this is important.
