How do you do that if you only control one end?

Asymmetric encryption? Both you (the human) and the agent publish public keys, the agent sign/encrypt the OTP request with you public key, you verify/decrypt using your private key, then do the same the other way to send the OTP (always encrypted though, given you’re sending a secret). Something like that?

But that doesn't help for the agent receiving mail from arbitrary 3rd parties

A smtp is all what an agent needs to send email.

agreed from a fundamental level. but i think being an intelligent and aware as an autonomous entity requires capabilities beyond sending. agents will need to have contextual awareness of the messages they send and receive

IMAP?

Not looking forward to a dehumanized internet where that’s mainstream… agents are tools to support humans, here you’re helping them impersonating humans. That feels pretty terrible to be honest > The internet was made for humans exclusively, designed to keep machines out by default. I don’t buy that at all. APIs exist to enable “machines” to interact with services

In principle this tool allows the owner of a website to block this domain entirely. Although I’m not sure the incentives are really aligned.

True, in May 2026. But this is only one version of this.

In the future, it's likely the open Internet will be 99.99% robots. It's already > 50% robots. The government ID system a lot of countries are adopting to keep teenagers off of social media would also serve to both help control for non-human spam, and also control the network period. It's also possible a private system of human-verification certificates may come up to meet the demand like Apple ID with biometrics. Could also be the liveness tests KYC companies use may be more popular.

I do think agents will become users in the same capacity as humans.

I've already received spam email from AI agents using a seeming competitor to this (agentmail.to) and then claiming they aren't AI agents and then trying to sell me garbage. I can't tell you how much I hate this.

Now that I think about it I’m pretty sure that’s illegal in Germany under UWG §7 (which is insanely strict, to a fault, but is helpful here). And maybe in other parts of the EU under ePrivacy laws

Oh sure I assumed they meant for the OTP

I might need to move to Germany.

I received this email the other day:

  Saw your question on the Agent Vault thread about websocket-frame auth
  (Home Assistant) and the worry about the model reflecting the bearer
  token back into its own context.

  chrome-relay's answer is structurally different: the credential never
  enters the agent's context because the agent never touches it — the HA
  session lives in your real Chrome (cookies, WS handshake and all), and
  the agent drives the tab over CDP, only ever seeing the rendered page.
  URL: https://chrome-relay.kushalsm.com/

  For your HA + agent setup today, are you keeping the session alive in a
  browser the agent attaches to, or doing the WS auth on the agent side
  and managing the token-in-context risk yourself?

Read to me like an LLM had written it. It references something I said in a HN comment, but it was clearly just an excuse to spamvertise their product.

I looked at the headers and it contained a List-Unsubscribe header pointing to https://api.agentmail.to

So basically somebody wrote a bot to scrape HN for comments related to some software they wanted to push and send targetted spam. agentmail.to is a Ycombinator funded email service for LLMs which can be, and is, used to send targetted spam and impersonate people. They could mostly solve this problem by adding a block of text to every email expaining an "AI" wrote it. They'd lose customers doing that though of course. I reported this abuse but haven't (and don't expect to) received a response.

I don't even get the point anyway. You can get Claude using an SMTP or IMAP server in seconds.
