I want a bulletproof way to give email sub-addresses, since some websites strip out special characters like + and .. I have an idea for how it could work, let’s say my email is [email protected] and I have the following:

  • All emails sent to TheTwelveYearOld@ get blocked
  • I specify a suffix that would be used instead of +, perhaps “From”
  • I whitelist phrases that go after “From”: TheTwelveYearOldFromDoorDash, TheTwelveYearOldFromGoogle, TheTwelveYearOldFromReddit

Are there any services that can do this? I’m thinking I should make my own domain for emails that way my email addresses aren’t tied to any companies and I can easily switch.

      Why use a catch all when you can configure postfix to use _ as a separator instead of +. and then you can configure dovecot to automatically classify the selector into directories!

        First purchase a domain. Cloudflare is definitely the cheapest but there are other options out there if you don’t want to use Cloudflare.

        Use an alias service like SimpleLogin or addy.io. addy.io has a cheaper ‘lite’ (limited) plan, SL has a cheaper ‘premium’ (unlimited) plan.

            They both will automatically create an address on-the-fly. Give a service [email protected] and it will automatically be generated and sent to your mailbox of choice.

              Thanks, I’ve been using proton on my custom domains so far, who seem to support catch all email addresses*, although I’d love also to have a feature where I could cut off an email if it gets too spammy, I think I’ve seen that on some other alias services. Do you know if that’s something simple login can do?
