postfix-tls status on sarge testing?

[Bernd Prager <bernd@prager.ws>]

Hi,

I just installed sarge and try to get postfix up and running again.
The postfix-tls installation brakes with:

    > apt-get install postfix-tls
    Reading Package Lists... Done
    Building Dependency Tree... Done
    Some packages could not be installed. This may mean that you have
    requested an impossible situation or if you are using the unstable
    distribution that some required packages have not yet been created
    or been moved out of Incoming.

    Since you only requested a single operation it is extremely likely that
    the package is simply not installable and a bug report against
    that package should be filed.
    The following information may help to resolve the situation:

    The following packages have unmet dependencies:
      postfix-tls: Depends: postfix but it is not going to be installed
                   Depends: postfix (= 2.1.5-9) but it is not going to
    be installed
    E: Broken packages

My sources.list contains:

    deb http://http.us.debian.org/debian testing main contrib non-free
    deb http://mirrors.kernel.org/debian/ stable main
    deb-src http://mirrors.kernel.org/debian/ stable main
    deb http://security.debian.org/ testing/updates main contrib

Any help would be greatly appreciated.
Thanks,
