Allow wildcard and full domain suppression
Allow adding address such as the following to suppress lists so that known bad domains can be preemptively blocked.

regex would work too

If gmail.con is not a real domain, then it should be added to a bad domain list.
If mailgun could even create a global list of bad domains, that would be great.
Just suppress bad emails. I'm okay with paying for the attempt to deliver the bad email, just don't send it. Please suppress it.
