Subject: www+nntp: deal with lack of addresses for ->ALL

Since extindex is an amalgamation of several inboxes, discerning
an appropriate address for List-Post: would be expensive and
most likely unnecessary.  Some legacy/historical inboxes may
have no active address, either, so don't attempt to set the
List-Post header if no addresses are configured.
