New alias domains
I attempted to make an account with New York Times on 6/3/2026 using a Proton alias with domain passmail.net and was told to "enter a valid email address". I think the domain is now possibly being added to blacklists. This is the first time I have encountered the issue.
It may help if Proton would once in a while add a new domain for aliases that we could use as a backup. As time goes on, "passmail.net" may be added to more and more blacklists, rendering the alias feature non-functional.

That's a valid concern. As more websites tighten their email validation rules, having additional alias domains available could help users avoid registration issues and provide a reliable backup when one domain is blocked.
