[Dovecot] To query two SQL tables for user verification over LMTP, should I use (a) two separate lookups? or (b) just one lookup with a boolean query?

So you're not using LMTP authentication to verify that Postfix is trying
to deliver to a valid user?  I though that's what it was for.

In your setup, 'who' does Postfix try to deliver to, then?  The 'real'
user, after figuring out and remapping any aliases to it? Or to the
alias, and then Dovecot does the remapping?
