It’s worse when you have a catch-all domain, especially if that domain shares a name with a blockbuster movie about to come out, or is in theaters, or was successful in theaters. It doesn’t matter if it’s .com, .org, .net, or whatever: spammers will forge under your domain and you’ll get the bounce-back, and some of the addresses they spam to will also be spammers. Those spammers will then harvest those addresses and spam them directly, creating a feedback loop that grows so massive that your ISP will disable your server-side filters because they’re too busy filtering the incoming spam, forcing you to close your catch-all domain to only those usernames for which you want to receive mail.

And then it will take hours for your ISP to open a new username at that domain instead of the mere seconds to whitelist it yourself, so you might as well register some obscure domain no one would ever want to trademark.

Though you may want to choose a domain that doesn’t contain any HTML tag names like “script” or “table” in it. Some sites will strip anything that looks like an HTML tag from your registered e-mail address, leaving you unable to receive your password verification link.
