I was getting the same error messages. Except for switching away from 
the external TNEF package, I believe I tried all the suggestions and 
settings mentioned and still had the problem.

Finally, I made this change to the TNEF.pm file:

--- TNEF.pm.orig        2010-09-17 04:52:58.000000000 -0400
+++ TNEF.pm     2010-09-22 11:08:43.000000000 -0400
@@ -235,7 +235,7 @@
                                "$dir/$unpackdir");
      return 0;
    }
-  chmod 0700, "$dir/$unpackdir";
+  chmod 0770, "$dir/$unpackdir";

    my $cmd = MailScanner::Config::Value('tnefexpander') .
              " -f $dir/$tnefname -C $dir/$unpackdir --overwrite";

This might not be the right answer, and I may have something else setup 
wrong, but since I did this I haven't had a single error.
