the server looks buggy to me, e.g.

>>> [06:55:03.249425] LIST
<<< [06:55:03.275944] 215 newsgroups in form group high low flags
<<< [06:55:03.345962] frrecmoto 0000000001 0000130715 y

the response should be "groupname highmark lowmark flag" (RFC 3977 7.6.3),
but the actual response is "groupname lowmark highmark flag".

SelectMarkGrpUnread ('z') in the top level can be used initially to work
around the issue, but it's a server issue not the clients fault.
