[Dovecot] default_mail_env auto-detect woes for maildir users

[David Friedlander]

I wanted to follow-up on my own message, because I have devised a usable
work-around for the situation I described yesterday.

======= dovecont.conf snippet =========
  userdb passwd-file {
    # Path for passwd-file
    args = /usr/local/etc/userdb.dovecot
  }

  userdb passwd {
  }
========================================= 

where the userdb.dovecot file has entries of the form:
joeuser:x:61375:20:Joe User:/home/joeuser:/bin/false::maildir:/home/joeuser/Maildir:INBOX=/var/spool/mail/joeuser/

Comments:
* This works, in terms of having "inbox=" properly defined for maildir users.

* I will be placing entries for each maildir user in this userdb.dovecot
  file (letting mbox users get handled properly by auto-detect of
  default_mail_env).

* I had to move the "userdb passwd" block _below_ the "userdb passwd-file"
  block in dovecot.conf to force it find my special entries first.

* I am pleased that I was able to get away with a literal 'x' (a la shadow
  password files) in this file, due to "passdb" and "userdb" being handled
  separately. Nice design of dovecot's!

This arrangement gives me the granularity to mix mbox and maildir users,
as I desired.

My question: Although this is a functioning work-around, is there
something I am not understanding or why is auto-detect not working?

Thanks in advance,
