I don’t know about signing, but my email domain (my surname.net) is now 30 or so years old. It gets^w got a lot of spam... A decade or so ago, I set up a catch-all account so <anything>@mydomain.net is redirected to an isp-account that I have as one of my email identities, In this case I used <account>@mac.com. It’s basically just a front-line imap repository, stuff I want to keep will move off it. Whenever I need to supply an email to an online site, I use <company name>@mydomain.net. The only time this hasn’t worked is with Samsung, who won’t let you sign up as ‘samsung@...’, generally it’s ok though. There is another rule on the mail server, send-to-trash. This accepts all email and just bins it. I can move <anything>@mydomain to this rule at the click of a button in a second or two on with a web-interface. I do this for: - unsolicited email sent to a random “name” at my address, this is actually fairly rare now that most of the obvious ones are gone - when the mail content doesn’t match the <company name> part, ie: where the address has been sold to an email-list. - when I want to expire the email address. Sometimes this is temporary, and I have an address I want to keep, but it’s current;y being spammed. Making the server send reject messages For a while usually helps. Usually. Using this, I’ve managed to keep the same email domain since college some 30 years ago actually useable and useful. YMMV :)
