This is usually not a problem. The first message is delivered upon
arrival (ie. _not_ kept in the incoming queue) and its Message-ID is
stored in recently-arrived messages database. The next one(s) to come
will be discarded by the recipe since its (their) Message-ID is already
in the db.

Read the `procmailex' man page and search for `msgid.cache'.
