[Dovecot] Trouble with %d in args of passwd-file

[Nathan Hüsken]

Hello,

I am trying to configure my dovecot folowing this guide:
http://www.w3style.co.uk/virtual-domains-with-exim-and-dovecot

I append the output of dovecot -n below. I created
/etc/vmail/my-domain.de/user containing:
test-user:{PLAIN}test:1002:100::/home/test-user::

No I try to login:
telnet 127.0.0.1 143
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
* OK This is Dovecot, and it is ready.
a01 LOGIN test-user at my-domain.de test
a01 NO Authentication failed.

It does not work! But when I change the "%d" to my-domain.de, and
login without the domain, it works!

What am I doing wrong?

Thanks!
Nathan
