Why does my DCC server refuse to accept more than 50 operations per second?
A common cause of such problems is one of the DCC server’s defenses against denial of service attacks. A DCC server cannot know anything about anonymous clients, or clients using client-ID 1 or without a client-ID and matching password from the /var/dcc/ids file. As far as your server can know, an anonymous client sending many operations is run by an unhappy sender of unsolicited bulk mail trying to flood your server with a denial of service attack. It is easy to tell your client its ID with the cdcc add or load operations.
