I've had people try to guess my login with Company ABC once they learned of my [e-mail] address. Avoiding the reuse of email addresses helps here, the same way avoiding the reuse of passwords does.

For blackhats, with catchalls you can create multiple accounts on sites that try to prevent it by assuming everyone only has 1 email address.

For me the biggest drawback is migrating ALL those emails if your provider decides to end support for catchalls (like Dreamhost).

With Gmail for Business / GSuite / Workspace, I had gone through the trouble of adding aliases through the Gmail.com UI when I wanted a from address. And I had created a bunch of dead accounts with aliases to reduce spam.

But when I switched away from Workspace to NameCheap, I just set up my one account as a catch-all, and in Thunderbird, when I want to send from one of those aliases, I just type it in, and it works fine. (Gmail had a setting that if you got it wrong, it sent it as an alias, but also used your mail address as the actual from/reply-to, which I found annoying!)

I also stopped bothering setting up those "honeypot" accounts. I get more spam, but... it's almost all detected as spam and put in the spam folder, so I don't worry too much. A few weeks ago, I had a day where a couple dozen gibberish addresses came in, like [e-mail], but then it stopped again.

Of course, all that is to say, if my current host does end support, it would be a pain!
