I like that this can also show you which addresses are sending SPAM without being sent from an actual IP address or domain (or even if they're just spoofed). It will help us decide who we let have our domains as well so it has helped cut down spam drastically - especially with DKIM! The UI could use some more work but overall not overly bad for something new coming out right now- though there's nothing wrong specifically when using older versions either way.- Using other services such SpamTitan gives me what i need already however DMA does do one thing better than them at least currently; its showing WHO sends emails via gmail /etc etc The service is very clear and easy to use. I have tried different ways to integrate email with my domain and this was one of the most simple. I am solving my own problem but you can't say it's not worth the money! Sometimes you need to wait few days for an update or change your settings to see results. We are using it as a way to protect our emails from spam bots and other bad people that try to steal them.
