That is why many list packages allow a person to have one or more post-only
aliases. There is one list to which I have two svbscriptions, one of which
is permanently in vacation mode, because it doesn't support post-only
addresses; there is another where I have two active svbscriptions and
receive two copies of every article because it supports neither post-only
addresses nor vacation mode, so that is my only way to have posting
privileges from two places.
