Hi i bought at fastproxyservers some public proxies. Now i need to check whether some of them are blacklisted for smtp. ZennoProxyChecker can perform this check, but it needs a source where it can download some proxies. The problem is that you need a password at fastproxyservers.org to see your public proxies. So i can t get the proxies into ZennoProxyChecker. Any solutions, how to mass check if socks 4 proxies are Blacklisted??? I m searching for f** hours.
