Hummm Thanks Jake.... i´ve read in the docs of chkuser in version 2.08 it was changed.
Note on version 2.0.8 NULL SENDER is now always accepted. This is a base rule of RFC, used by rejected messages, read and delivery receipts. Old settings related to NULL_SENDER are now not working anymore.

They are usually bounce messages. If you do not allow them, then your server would never get bounce messages from other servers.
