I've used a like technique with over 45 million records present.  Was
extremely fast.  Beat the pants off SQL for the kinds of things this is good
for, which is: ... simple key:value lookups

It's called experience.  I could explain many cases where SQL is overkill
and overhead.  But I don't do mail servers very much, so it would all be
off-topic for this list.  This is not the SQL/NOSQL battle zone.

yes it is, if you only have a small number of users.

Why would it be any slower if the 45 million records represented users
instead of document IDs?

No such button.  That's one of the reasons why mailing lists are lousy.  Oh,
since this is a list about an aspect of mail servers, I suppose it seems
natural to communicate over a mailing list.  OTOH, some people might need to
communicate when mail isn't working.  That's one of the reasons I acquired a
Gmail account for this and Postfix subscription.  So do you know a freemail
service where there is a "reply to list" button?
