relay to /dev/null

I’m using sender_dependent_relayhost_maps. Is there an option to route a domain to nothing? @example.com /dev/null In there now, which of course results in an error, but also has the desired effect. What’s the graceful way to do this? Thanks! -jeremy signature.asc Description: PGP signature

Mail looping issue
