Network News Transfer Protocol (NNTP) Additions to LIST Command
Abstract
This document defines a set of enhancements to the Network News
Transfer Protocol (NNTP) that allow a client to request extended
information from NNTP servers regarding server status, policy, and
other aspects of local configuration. These enhancements are made as
new keywords to the existing LIST capability described in RFC 3977.
This memo updates and formalizes the LIST DISTRIBUTIONS and LIST
SUBSCRIPTIONS commands defined in RFC 2980. It also adds the LIST
COUNTS, LIST MODERATORS, and LIST MOTD commands, and specifies
additional values returned by the existing LIST ACTIVE command for
the status of a newsgroup.
