dovecot - Jan 2013 - %d in configuration file does not work

I am trying to set up dovecot in a postfix virtual account/domains setting.
In the configuration file I would like to use %d in two places, for:

mail_location = /var/mail/vhosts/%d/%n

and to specify the location of the respective passwd file:

passdb passwd-file {
   args = /etc/auth/%d/shadow
}

Looking at the logs, %d is empty while %n works, so dovecot is looking for
something in  /var/mail/vhosts//myname and /etc/auth//shadow which don't
exist. Replacing %d in dovecot.conf with the actual domain name works.

So, the quesiton is, why is %d empty, and from where does it take its value?

This looks like a pre-2.x Version, best to share that
detail.

Hard to tell without seeing the actual logs. My guess is the login is not in
user at domain format:

Indeed, this is the output of "dovecot -n":

How can I get the login in the user at domain format?
