Be careful, my domain got on a whole bunch of ISP’s spam lists because I had done the same thing.
They really don’t like open domain email working.
I have a set it up so that any email sent to unknown users on my domain gets redirected to email. If you send an email to bad_address@example.com and my real email is uranibaba@example.com, I will still receive the email.
Now this is great because I will just use name_of_service@example.com and still get the email. If the email is leaked, I will know where it came from.

That’s annoying! It’s not been my experience, out of curiosity do you have any theories why your domain/aliases got blocked?

For my domain it was put on a spam list that various ISPs use.
When I spoke with one ISP they said it’s because I had an open email address situation going, where a spammer can send a spam email out to a third party and on the reply address to they can make up anything as an email address for my domain name and it would be ‘valid’ because my domain email server was set up to receive all emails that you described.
And because of that I got put on a global spam list which many ISPs use. At the time I didn’t even know about my domain being on the list, I just noticed a big drop in emails I was receiving.
FYI this happened over a decade ago, so I do not know if that is the current practice today. But better to make sure any email addresses to your domain that is not valid does not go through. No “catch all” bucket situation.

That’s not because you have a wildcard. That’s because you need to implement DKIM, DMARC, and SPF records to prevent others from using your domain name to send mail.

Owning your own domain is great that way. Even makes the little bit I pay to ProtonMail well worth it. There are a few addresses I have dedicated, like my aws@example.com, me@, and my-name@, but the rest just go to a catch all. It’s fantastic.

My mail is hosted by my domain host but I am considering switching to Proton. Have you done such a move?

I made that move and had no issues. You can copy/paste your way through DNS setup and the rest is just configuring your proton account how you want.
You’ll want to be familiar with proton and some of the tradeoffs in its privacy model, but it’s most likely more feature-full than a hosting provider. Dreamhost, for one, is quite basic.

Yeah the setup is pretty trivial and it works great.
