Yes. I have dozens of domains that I use for email. I create throw-away addresses per-site, per-use-case. If one of them starts getting abused, I either remove the alias, or set up filters to only allow specific content to that address. One of them is in my profile here. As a bonus side effect, I can tell when a business or organization has either been "pwned" or has otherwise sold my email address to other entities. Some domains I point to fastmail so that family members have an alternate to gmail. The remaining just point to my VM that runs postfix and drops all the email into virtual mailboxes and I read them from the shell. This has worked great for decades.
