Apparently you're using the sasldb2 database for logins?  If so, the 
sasldb2 database needs to be readable by postfix, and it has to be 
populated with the usernames at domains that you need.  Have you populated 
the db?

You would probably be better off using saslauthd as your pwcheck_method. 
  Then start saslauthd with the -a sasldb flag.  (See man 8 saslauthd.) 
  Auxprop is an older method that wasn't very dependable.
