Apologies for noise, havn't got an answer to this anywhere else. Trying to prevent spam coming into the fm trac ml. created from add ticket in the fm trac. If in the mailman admin > privacy -spam-filter as 1st rule I put:- if ^Subject:.* != ^Subject:.*\Wstuff\W action > discard Will it discard all Subjects that don't contain "stuff" Which is what I want. Currently have in place: ^Subject:.*\Wstuff\W (action > accept) which still lets the odd spanner through. Or would this all have to be done in a backend file somewhere. Trying to learn Python on the wing. -- Regards, Frank "Still trying to learn, both old and new tricks" --me . _______________________________________________ infrastructure mailing list infrastructure@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/infrastructure
