fetchnews could move the raw message from out.going to a new 
sent.messages  directory instead of unlinking them.

A wrapper script that manages the start of fetchnews could do 
that, too. 

process messages in out.going
run fetchnews
process messages in sent.messages

. or such

One problem will be rfc threading of mail messages. There is
no message-id: line in mails and no xref: .  
Threading on subject: it the only way to collect a thread 
of mails.

'-' as prefix sounds good. '-' is part of many group names,
so this character must be allowed. I'll look into the RFC 
whether it is dissallowed for the first character of a groupname
and report success to the list later. 
Currently I don't have a working leafnode installation.
