I think it should work with the following in local.d/multimap.conf:

FILENAME_BLACKLISTED {
  type = "filename";
  filter = "extension";
  map = "$CONFDIR/local.d/filename.map";
  action = "reject";
  message = "A restricted file type was found";
  skip_archives = true;
}

filename.map itself only contains the suffix of the files to be blocked, 
e.g.

vbs
dll
exe
com
