Users of filter.nostr.wine
Amethyst's Outbox has a relay section just for you. Your *filter* relay should go in the *Proxy Relay* section of your relay settings. It will disable the outbox model and only download feeds/posts from filter.nostr.wine 's aggregator.
If you want the broadcasting feature of filter, add the relay to the *Broadcast Relay* list and all your new events will be sent there to further broadcast your content.
You can remove filter from all the other lists since that relay doesn't really do anything else.
