I ran into a similar error during my install, but I don't recall if this 
is what got me around it:

On the Front end:
virtdomains: on

On the Backend:
virtdomains: userid

On the Mupdate server:
virtdomains: on

I have Postfix and lmtp (proxy) running on the frontend as well. I can 
provide more config if you'd like.
