OK, I've just implemented IHAVE support for nnrpd (but not committed
it yet), here's what I've done:

Require Date, From, Message-ID, Newsgroups, Path and Subject headers

Add X-Trace and X-Complaints-To unconditionally (stomping on anything
the client supplied)

Suppresses generation or alteration of NNTP-Posting-Host,
NNTP-Posting-Date, Organization, Lines, Cc, Bcc and To headers

I haven't made the X-Trace and X-Complaints-To headers configurable
yet - yes I know thats wrong according to the RFC, I just thought I'd
ask here first for peoples views.

I'm about to rewrite READline so the line length limit goes away which
fixes one of the problem cases I can't otherwise easily work around
for POST/IHAVE differences.
