We have been removed from UCEProtect1 Blacklist so at this point our mail server is off all public blacklists.
Yahoo still appears to be blocking us in spite of the fact that I’ve made two requests to be removed from their blacklist, 48 hours apart, per their policy. I received only a bot response the first time and no response the 2nd.
I don’t know if it’s part of their business model to try to kill other providers by blocking their e-mail or if there are no human beings there to respond to requests or just what the story is but it’s frustrating.
