See description below for more information before using this feature. Also, see the KNOWNBUGS entry regarding bestmx map lookups. Make sure your .cf is up to date with your .mc? I also found around the 8.9 series that a certain order of the .mc entries needed to happen. For instance, defines must come before other things because they 'active' features. I don't know if this was a bug or what, but this is my order: includes defines MAILERs MASQs FEATUREs So more things around and rebuild your .cf I also cannot recommend this enough.
