This is the only thing blocking me from switching to protonmail. My email service (fastmail) has unlimited aliases. They also have about 100 domains you can register these aliases to such as fea.st, proinbox.net, fastmail.net, speedymail.com, etc... If you guys had this and a bunch of random domains we could use I would switch. One thing that fastmail got wrong in their implementation is allowing aliases that are deleted to be used by other people. I ended up picking up an alias that had been used by someone else and getting all their mail. An alias should be permanently unavailable if someone else claims it, even if they subsequently delete it.
