It is my impression that nntplib was and maybe still is a bit flakey on 
3.0.  3.0.1 will be out this month and may or may not have improvements. 
  I am fairly sure that updating it to a newer RFC would be welcome. 
Such upgrades have happened to other protocol modules when there has 
been someone willing to do the work.  Please do check the tracker for 
existing nntplib issues and add one if appropriate.
