Issues registering an account using either Protonmail or Tutanota

Protonmail and Tutanota email services are free and open source and they use end to end encryption for email services. I am not too sure what is going on but when I am trying to register an account over at a different website that uses discourse, when I have used both Tutanota and Protonmail for registration, discourse claims that it has sent an email to the specified email but I end up not receiving anything in my inbox. I have checked the spam folders as well but nothing turned up. I have even resent the verification code but I still get nothing, which is getting rediculas. I have never had this issue when registering with a Google account. Why does discourse which is also a free and open source platform, forces users to use corproate owned email addresses rather than allowing users to use whatever email address they please to use?

We don’t — if the email is being sent but silently rejected (as spam or unwanted) by the email service, you would need to contact proton mail to figure out why.

Outlook / Hotmail is notorious for silent rejection of email they don’t like, by the way. This is not unheard of.

But that is werid how both Tutanota and Protonmail does the same thing, even with disposible email addresses that I have used in the past the same issue occurs.

Which service did you use to register here?

I was registering to ARchLabs that uses Discourse, and I had that issue as mentioned above.

Sure, but which service did you use to register here on meta?

I used a Gmail account.

So have you had problems registering using Protonmail to more than one Discourse site? Did you try to register here on meta with Protonmail before posting this?

You really can’t say that unless you can establish some pattern which suggests Discourse sites have a problem routing email to Protonmail. One occurrence doesn’t make for a pattern.

안녕하세요
저도 Protonmail에서 비슷한 문제를 겪고 있습니다.

저희 Discourse 구현의 관리자 계정은 protonmail 계정입니다. 대부분의 이메일은 정상적으로 수신되지만, 관리자를 변경하려고 했을 때 확인 이메일(또는 테스트 이메일)이 수신되지 않았습니다.
스팸 폴더도 확인해 보았지만 아무것도 없습니다.

+1입니다.
같은 문제입니다.
다른 메일 계정으로 테스트해 보니 정상적으로 작동합니다.
일반적으로 새 스레드, 스레드 답변, 초대장 같은 디스커스 알림 메일은 받을 수 있지만, “관리자 권한 부여” 확인 메일이나 테스트 메일은 받지 못합니다.
다른 주소로 테스트 메일을 보내 봤는데, 프로턴메일(Protonmail)에서는 받은 편지함에도 스팸 폴더에도 메일이 표시되지 않습니다.

문제가 프로톤 메일에만 있는 것이라면, 프로톤 메일이나 메일 전달 서비스 쪽의 문제입니다.
