What is this in that case?

Unfortunately no. See here

Disposable mails (one time mails) can be a problem for webmasters. But PRIVACY mails or ALIAS mails is PERMANENT addresses. So there is no way that they would be deleted at no additional situation. They gonna be deleted only if webmaster send SPAM or got data leak.

If you will use such addresses as disposable you will be simply banned (there is written in ToS)

Moreover you can use this website (it generates temporary working Gmail addresses) or this website where is new domain name every day

You are telling truth unfortunately. That’s why I asked help from community…

They rejects them because it is an abuse prevention mechanism. You can solve captcha and register without any additional information

Your can simply block sender, not only delete aliases. So it is a problem of webmaster that doesn’t respect users wish to unsubscribe

I don’t understand why to block anonymous mail services when it is temp Gmail services exists (just search “temp Gmail”). Example

deleted by creator

Look. Outlook, Yahoo, ICloud, even Gmail provides temp mails solutions, but nobody complains or blocks them.

Also you can use something like this that will create disposable Gmail every time. So blocking Proton is totally useless

Devs can use them to block DISPOSABLE mails, not PRIVACY legitimate emails. That’s why it is critical to remove privacy oriented email domains from such lists

Unfortunately? This is true. That’s why I asked help from community!

You can try by yourself (without “grey” ip)

Unfortunately, I contacted support of some local websites, and they said that they wouldn’t white list any domains and I need to contact this list owner

We fighted it out from 7c filter. Now only this and this lasts. Thank you for kind words. Only community can change this bad practice!

Yes. Aliases is not disposable mails. Moreover SimpleLogin (Proton aliasing service) forbids to use it as disposable in ToS

You can sign up on Outlook anonymously too. Look video in this comment

He thinks that it is because of anonymous registration. But Outlook provides it too…

That’s why I posted this. I hope we will find a way to unblock Proton

Also this list blocks it too https://github.com/wesbos/burner-email-providers/issues/422

Please help!
