AFAIK news.cis.dfn.de run a modified INN 2.x, the other one is
unknown.
But I did overlook good old

| 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.)

| uses them anyway; this avoids any possibility of
| confusion.

| Implementors of relayers and reading agents are
| warned that it is intended that the successor to
| this Draft will change the definition of ng-delim
| to:
|
| ng-delim = "," [ space ]
|
| and are urged to fix their software to handle
| (i.e., ignore) white space following the commas.
| Meanwhile, posters must avoid inserting such space
| (despite the natural-language convention which
| permits it) and posting agents should strip it
| out.

(The second paragraph addresses multi-line Newsgroup: headers, which I
mentioned in another article concerning mgetheader().)
