Ok, if you go to Amethyst, you will see 7-8 relays in inbox and Outbox. That's too much.

Select 3 from Outbox trust to keep your posts. This could include paid relays. nostr.wine (if you are paying) is great here.

Select 3 from Inbox that are open to anyone to post. nos.lol and nostr.mom are great here.

For Private Inbox/DM relays add:

- nos.lol

- auth.nostr1.com

- relay.0xchat.com
