I've got a custom domain that's very similar to a law office & the owner of the law office and I have the same name, so I often get emails from the courthouse, clients, other lawyers, etc who must have written his email address down (he appends `law` to the end of the domain, while I do not). I'm very frequently forwarding these messages and saying "I've deleted this on my personal account", but they don't seem to stop - has been happening for years. Seems like something he would want fixed. One time, I even responded to another lawyer to tell him and he thought I was the intended owner and started riffing with me over email!
