Progress (I know you are all reading this with bated breath in eager anticipation of my next missive).

I changed the user_query to 

select 89 as uid, 125 as gid, concat('/usr/local/virtual/', maildir) from mailbox where username = '%u'

and got a new error, which I think reveals the source of the problem:

Error: user lists@*munged*: Mail access for users with UID 89 not permitted (see first_valid_uid in config file, uid from userdb lookup).

So, I set first_valid_uid = 89 and I get a NEW error.

So, the uid and gid are now correct, the maildir path is correct, and it is STILL not happy.
