Yeah I know this might sound ridiculous for some users. But this is to prevent some users from using CloudCone’s servers to send spam mails resulting to Bad IP reputation. It’s so hard now to find Good IP from CloudCone because of those spam users. Most of the IP is blocked on outlook. Thankfully I got good one after destroying and recreating my server many times. Once this is implemented, the user can send request to allow SMTP outgoing ports for their servers and CloudCone’s support should evaluate the requesting user If they can open it for them by asking questions like where are they going to use it.
Thank you. Sorry for my bad english.
