Domain names for catch all email aliases (lemmy.ca)

I'm looking into getting some domains for email, so I don't need to use the same few addresses for everything. In doing this, the domain name itself becomes the identity, but it's also entirely arbitrary.

What is a good method to choose domain names so that they look more or less normal? Catch all addresses can of course be detected in SMTP, but the idea is just to not look suspicious. Would anyone be comfortable sharing the constructions they use? (though not the domains themselves, for obvious reasons) Should I use subdomains for the things that can safely be correlated, (as spam defense) or is it better to only use different mailboxes on one domain?

I set up my postfix server so that anything after a hyphen ("-") becomes a wildcard. It like Gmail's "plus addressing", but the hyphen is more subtle. It means multiple users can make infinite aliases on one domain.

So, "user@domain.com" has the same mailbox as "user-somesuffix@domain.com".

How did you do that?

I'm not OP but I use mailcow to host my mail and it comes with the + aliases by default. So mail+google@example.org goes to mail@example.org.

You can also do fully random aliases on demand, both time limited and permanently. Useful for those few services that do not accept + in their email fields.
