This will set content_filter to the last specified value. Postfix
parameters are scalars, not lists (list are specified with tables,
and there is no list-based variant of the content_filter variabe).
What do you mean with parallel? There is only one mail flow, so
it can flow through only one filter at a time.
Therefore, the answer depends on what you want: apply one of the
two filters or both filters (in series).
