Hi Joey,

I recall that I have added code to leafnode to sidestep this exact
problem, but I no longer remember which leafnode version I added this
to, and I seem to only find this in leafnode-1.  There is currently no
support for alternative newsgroup layouts in any leafnode version that I
have released.

A recent leafnode 1.11 version would store net.micro.432 in
/var/spool/news/net/micro/-432 to avoid the issue, but I suspect you
might be using leafnode 2.*.alpha*, and I'd have to forward-port the
leafnode-1 code (which would not happen before next week).

Which leafnode version are you using exactly?

(Just a minor nit, the Subject confuses message-IDs with leafnode's
article numbers. The message-IDs are in /var/spool/news/message.id/NNN
directories, where NNN are numbers between 0 and 1000 exclusively, and
look vaguely similar to email addresses.)
