Hello. I'm using oxwall from my x10hosting account and I have been having a problem with my mass mailing and password recovery. They said this is due to the host. I need help but I don't know what to do.
Well, "mass mailing" on Free Hosting means no more than 100 emails in any given (60-minute) hour. If you've gone over that at any point, you're likely greylisted by the system.
