@dan: I kept originally had my apt broken with "E: Unmet dependencies.
Try 'apt-get -f install'", and actually running that broke it (and
ruined the next day for me..) Basically if you run it, you'll get your
package manager back, and then you need to run dpkg -i --reinstall again
on the 2.1.23 packages and you'll be good to go. If you try to do any
apt-get dist-upgrade or install something that is related to
sasl/postfix it WILL try to upgrade your sasl packages, do NOT do that
or you'll break your system again.

It's better to be able to install other stuff that you need and not have
a crippled system until a viable update is in place. Nothing worse than
trying to setup software without apt because you're afraid to update :P
best of luck
