My email address reachability is "unknown", its a fastmail hosted account. Quite a commonly used service. Is an unknown classification supposed to be treated as "I don't know, probably safe" or "I don't know, probably don't accept it" ?

{ "input": "***redacted***", "is_reachable": "unknown", "misc": { "is_disposable": false, "is_role_account": false }, "mx": { "accepts_mail": true, "records": [ "in2-smtp.messagingengine.com.", "in1-smtp.messagingengine.com." ] }, "smtp": { "error": { "type": "TimeoutError", "message": "future has timed out" } }, "syntax": { "address": "***redacted***", "domain": "***redacted***", "is_valid_syntax": true, "username":…

    {
      "input": "***redacted***",
      "is_reachable": "unknown",
      "misc": {
        "is_disposable": false,
        "is_role_account": false
      },
      "mx": {
        "accepts_mail": true,
        "records": [
          "mx.zoho.com.",
          "mx2.zoho.com."
        ]
      },
      "smtp": {
        "error": {
          "type": "SmtpError",
          "message": "permanent: 5.7.1 Email cannot be delivered. Reason: Email detected as Spam by spam filters. "
        }
      },
      "syntax": {
        "address": "***redacted***",
        "domain": "***redacted***",
        "is_valid_syntax": true,
        "username": "***redacted***"
      }
    }

I use @ .

This looks fantastic --- can you share some tips of setting it up?

Would you mind sharing your experience on how well that has worked for you? Has the complexity of maintaining different addresses been a problem? I ask because it is something I have always thought about, but I suppose I kept hoping a service would come along and magic the solution for me. Kudos on making it happen!

I'm not OP but I do something similar, which I can describe. I don't whitelist addresses, I have a domain with a catchall account. So I make up addresses as needed. When I want them to die, I add them to a ruleset on the server that punts them into the bit bucket. So far it has been really great. Easy, effective. Edit: Like the other reply you got, I use FastMail for this service.

There is a service for that: https://anonaddy.com/ I've used it briefly for testing purposes and I have no complaints about it, it delivered what I expected with no hiccups.

Could someone spell out a use case for this? One that comes to mind would be validating that a mailing list doesn't have any outdated email addresses in it, but couldn't that be determined by just checking for a bounce when a message is sent to it? I tried to sign up for SiriusXM the other day, and though I could create an account with my .pro email address, I couldn't actually sign up for service with that same addr…

I just watched a video where someone demo’d GitHub Copilot by writing a comment along the lines of // IsValidEmail takes a string and returns whether it’s a valid email address The AI response was a nightmarish 100+ character regex that made my blood curdle. I think of email validation like encryption: don’t roll your own, and don’t trust an AI to do it either. Edit: Here's the regex: https://gist.github.com/cassidoo…
