I'm still not convinved this is the right approach.

Yes.

I'm not sure about switching to Maildir. I definitely think Maildir is a
major improvement over mbox, but I'm worried too many things still
depend on /var/spool/mail/$USERNAME to be where the user's mail is at. I
could be totally wrong, but we need to check it.

If we focus on the SASL stuff for a little bit, IIRC my last proposal
was to make postfix's init script do something like:

if [ -x /usr/sbin/dovecot ]
then
    # Use http://pastebin.ubuntu-nl.org/46677/ to grab the socket path
    if [ ! -e /etc/postfix/dovecot_sasl_configured ]
    then
        # Set the SASL stuff up (like in your debdiff)
        postconf -e 'blahblah'
    else
        SASL_SOCKET="`parsestuff "auth default" "socket" "client" "path"`"
        mount -o bind "${SASL_SOCKET}" /var/spool/postfix/private/auth
    fi
fi

How does that look?
