I run an email marketing database. You might be pleased to know we keep a little "wall of honor" of the best fake emails we've been given.

> the best fake emails we've been given

If I were to do this, the email wouldn't be fake!

I have hundreds of email aliases on my (main) domain, and the list keeps on growing.

I have a catchall for my domain, so most sites get a unique website@mydomain.com email and a unique password. Not only does is help against password leaks but I also can find out very quickly if someone sells the unique address.

I have a 3 character plus tld domain for this purpose. I used to run my own server with Postfix and Dovecot, I was able to deliver mail and it all worked but Microsoft can do the same thing for less money and effort.

The best part of running Postfix was I could add domains and addresses to a denylist and it would bounce the email and the senders server would often put a REJECTED message in their inbox. The email equivalent of slamming the door.

Care to share any?

Most of them are just various conjugations of swearwords or attempted script injections.
