I had wildcard emails on my domain for a long time. I gave it up after a spammer decided to try a gigantic list of email usernames with my domain. They wanted to spam a hundred thousand separate users, but ended up spamming me a hundred thousand times instead. After that, I switched off the wildcard and just set up a normal address. This would probably not be as big of a deal if it happened today. This was in the early 2000s and the tools (at least that I had) didn’t deal with huge volumes nearly as well as I expect Google would. But I still haven’t gone back.
