because the lack of the CAPABILITIES is enough to tell them that it is not a mode switching server...

  if CAPABILITIES then {
    if MODE-READER then {
      MODE READER
    }
  else
    // not a mode switching server
    // use standard article retrieval commands
  }

plus they could simply look at HELP and see if CAPABILITIES exists instead of issuing a command that could fail...

 RC> thunderturkey doesn't issue that command before issuing MODE READER

interesting... i've never looked but t-bird is one of the news readers i use to test my news server with...

 RC> Neither does PAN, or KNode..

 RC> thrunderturkey just ignores the 500 response and issues LIST.

seems that more than one news reader has it wrong, then... or maybe t-bird has it right and the others are wrong for terminating...

 RC> I'd have to dig through the RFC, but I would say that is wrong..

the RFC can't be wrong... the RFC is what the rules are... software has to comply with the RFCs it supports...
