I would say that those things are broken then. If we decide to go with
Maildir, then we should just append 'dir=~/Maildir' for every
pam_mail.so in /etc/pam.d. Other than that, some minor changes
in /etc/login.defs (optional). If program doesn't respect pam or
login.defs, then it's broken :)

I see some problems with it, but this could be explained in
documentation (i.e. if someone configures auth mechanism in main.cf
and leaves dovecot_sasl_configured, it could get funny). But I do like
the idea, maybe we should use postconf to find out if auth mechanism is
configured and then decide what to do...

LaMont?
