Wish every provider would support this as I’m sure spammers have caught on to the plus addressing scheme.
Pharma spam, 419 scams, password leak crypto blackmail... remember that these miscreants rely on low costs to achieve their profits, so any sort of filtering is too expensive. They don't even filter out abuse@, postmaster@, hostmaster@, or mailer-daemon@.
You can use a shared domain:`hackernews@snorremd.kopi.cloud` Or, after setting up an MX and a TXT DNS record, you can use your own domain: `hackernews@mail.snorremd.com`.
You can change the "real address" of any "forwarder" (`snorremd.kopi.cloud`/`mail.snorremd.com`) to relay to any address you want, whenever you want.
You can block individual addresses like `hackernews@mail.snorremd.com` with two clicks starting from your mail client.
You can also configure individual addresses to redirect to RSS so you can read newsletters or other "chatty" services as part of your normal browsing habits.
