[Mailman-Developers] anti-spam filter

[Pratik Sarkar]

Thank you Terri and Stephen for your replies and explaining the whole
procedure of selection.
Coming back to the project,do we need to write patches for the SpamAssassin
or SpamBayes(which are integrated in Mailman) or do we need to start over
and make a whole new filter and start reinventing the wheels?
And somewhere I read that the filtering of messages posted by
non-subscribed members are done manually.Can it be changed to be filtered
automatically somehow?
Regards,
Pratik
