Hi, is it possible to load some type of blocklist into the PMG, to block sending to temporary mail Provider. I need this to stop spam registrations on a service using my mail server.
I think it's not described clear enough above. I have a service, where everyone can register with a e-mail and I want to block sending the registration mail to specific domains (mostly temp-mail provider). The problem is the software itself doesn't support this, but the are send by the pmg, so it would be nice if I can block them there from sending.
