which relay software has IMPLEMENTED OUTBOX ? or is it only on client side?
WoT model will never bring NEWCOMERS easy freely to nostr it will protect those who are already IN from junk in spam
decentralized and censorship resistant means smart USERS try stay under the radar
so go check their relays exclusively you will NOT miss anyone. its kind GO PULL and not WAIT PUSH FEED come
 

 Filter.nostr.wine has mailboxes. 

 >>Filter supports NIP-65. Your events are automatically broadcasted to your first 4 "write" relays and the first 4 "read" relays from the first 5 tagged users.<<

It's pretty sweet. Have it on the Laeserin npub. 

 um, yes outbox is a client feature for discovering relays to pull your feed from, based on where your frens are writing to.
