only allow certain TLD e-mail
Is there a way we can only accept mail from the primary TLDs? and maybe a few selected alternate specific domains?
essential we just want to flat out block all the new spam TLD addresses so users don't even get them in the quarantine.
I do want to continue scanning e-mail from the primaries, so I don't think whitelist is the way to go.
Maybe not even fully block, but apply a lot more stringent scanning policies to non primary TLD?
