There was a typo in an earlier config item:

auth_username_format = %Ln at Ld

Maybe that was what someone was screaming at me about when I looked at
username_format.  I didn't see this until I was trying to figure out why the
passwd file wasn't being read.  I ran strace, and saw that it was trying to
access a file with "ld" in it.  Even then it took a while because the domain
had been reformed as "Ld" and subsequently lower cased later.

I found this while trying out a subset of a couple suggested configurations
with some virtual_* settings in Postfix, and using dovecot/deliver via
transport.

I will now clean up the mess and hope I don't break it doing that.  Then
slam it with email and see what happens next.
