Capitalized letters in newsgroup names are a problem because it is
not strictly defined whether newsgroup names should be case-sensitive
Son-of-RFC1036 defines the content of the Newsgroups: header as
Newsgroup names MUST not contain uppercase letters, except
where required by encodings in encoded words.
It says, however:
NOTE: Possibly newsgroup names should have been
case-insensitive, but all existing software treats
them as case-sensitive. (RFC 977 [rrr] claims
that they are case-insensitive in NNTP, but exist-
ing implementations are believed to ignore this.)
The simplest solution is just to ban use of upper-
case letters, since no widespread newsgroup name
uses them anyway; this avoids any possibility of
Most servers where I encountered the problem so far (e.g.
news.microsoft.de) did treat newsgroup names indeed as case-
insensitive; therefore 1.9.4 (in contrast to 1.9.2) did so as well.
Apparently, INN does not like this:
~% telnet news.uni-marburg.de nntp

There is no easy way to fix this in leafnode-1.9.4; it might be
necessary to downgrade to 1.9.2.
