These groups will not be listed after a NEWGROUPS command because
in groupinfo they have a creation date of 0.

Leafnode cannot rely on the upstream servers doing all the sanity
checks on a message.

I think is is necessary to check the entire head before accepting an
article to post. This would include syntax checks on certain headers.

Documented bug. How could group directories be safely distinguished
from other /var/spool/news subdirectories, which should not be subject
to expiry?

Here, the new posting need not show up.

The problem is here.
GROUP advertises an article range which includes the new article, but
XOVER doesn't know about it.

Texpire shouldn't delete empty local group directories (using
readlocalgroups() and islocalgroup() when appropriate), and
(in nntpd.c) dogroup() should not fake a "0 0 0" line if the group
directory is empty.

At least one of my upstream servers outputs a first article number
higher than the last article number in its LIST ACTIVE and GROUP
response for an empty group. I haven't tried to implement this
behaviour into leafnode yet; I'm unsure if it would lead to problems
(it shouldn't).
