Does Proton block suspicious emails without making it reach the inbox?

I know there is a section for potential spam mails. But I wonder whether Proton block some of them so that they won't even reach that section. I am using it as my primary email right now and recently a recruiter tried sending me an email for tech discussion but it never reached my inbox. They were sure it was sent, and I later received it on my alternate email (gmail). Is there any possibility that this could have happened for other reasons?

If the recruiter sent an email from a domain that wasn't properly configured (DKIM+SPF, etc) then it would have sent a bounce email, which may have gone to the recruiter's span folder, or they may have ignored the bounce email thinking it was a phishing email.

Does Proton actually bounce if the sender is not properly configured???

It depends. They, like all mail services, will follow DKIM and SPF so if someone has DKIM+SPF set on company.com correctly and someone sets up a newsletter sending from mail.company.com, that's a misconfiguration that causes Proton, Gmail, Yahoo, AOL, Microsoft, Apple, and all the other large players to bounce the email.

yeah i think this might be the reason, but i don't know how to avoid this since it's an issue from their side

Nothing you can do until they fix it. If they really want to recruit you that bad, ask them to send the email to themselves and forward it to you.
