UPGRADING TO LOTUS NOTES 6 AND LOTUS DOMINO 6
Removing NNTP documents from the Domino Directory
Lotus Domino 6 does not support Network News Transfer Protocol (NNTP); however, the Lotus Notes 6 client continues to support NNTP. When you upgrade a Domino NNTP-enabled server, the upgrade process removes the NNTP executables, the NNTP value from the Server Tasks setting of the NOTES.INI file, and the News tabs from the Server document. However, the upgrade process does not remove the NNTP documents from the Domino Directory. You can delete any NNTP connection documents, including connection documents that accept newsfeeds, that push out newsfeeds, and that create a dial-up or LAN connection for NNTP purposes.

Note If you maintain a mixed-release environment with servers that are NNTP-enabled, do not delete any newsgroup databases because those databases are required to read newsletters.
