There are times where you just can't... someone uses my email address in person at tractor supply co. and I'm getting a ton of marketing email I can't usnsub to.

I've had this happen several times... There's a lawyer I used for a dispute a few years ago, and they now have another "First Last" name that matches mine, and he keeps emailing me... my reply, "Wrong Michael, again..."

It's kind of annoying all around... I need to get off my butt and get a few things shifted, then just start relying on my own MTA again, instead of forwarding *@mydomain to my gmail to. I'll still wildcard the domain, but to a single mailbox on my own mta.

I'm not sure how bad the spam might get though... I've had a test account on my mta for a couple years and it hasn't really recived any... my wildcard accounts either... I use the wildcard so I can do things like walmart@mydomain, to see if/where an email address is sold/leaked from regarding spam.

Contact the Bar Association for that lawyer's state. He will definitely stop making that mistake then.
