Pointless paranoia really, but imagine this: someone could subscribe to the same mailing list as you, with an address starting with 'a', so they get the messages before you, then send you messages with the same Message-ID as each message on the list. If their messages reach you first, the real messages could be deleted by your formail script. Edmund
