petidomo/subscribe.c
Peter Simons 0670963e12 When a un-/subscribe command needs confirmation, the request for
confirmation is sent to the address that is supposed to added to or
removed from the list. If, and only if, this address is different than
the one from which the request came, a short mail is sent to the
requestor to inform him what is going on.
