[ncc-services-wg] RFQ: Selectively blocking senders from distribution on mail list server side

Dear NCC Services WG, BrainMill has recently been forced to adopt a policy of blocking certain list members of RIPE mailing lists due to the content having negative information value. BrainMill wishes to petition a feature addition to the RIPE NCC mailing list servers: As a list subscriber I would like to be able to manage a FROM based permit/reject filter effectuated on the mailing list server side controlling distribution to my own subscription. The benefit of blocking specific sender's from further distribution to list subscribers includes less wasted energy in processing blocked senders. Perhaps Sieve would be an appropriate filter technology. Best regards, -- Martin Millnert BrainMill AB https://www.brainmill.com
