I bought the service today. I can say Its a great service.
I followed instructions. I can send mails and I can get mails. On the last step(I followed the video on blackfriday site) I created 2 SSL certificate for mail and webmail subdomains. they are cnames.
Webmail worked immediatly. but when ı go mail subdomain It says unsecure connection. How can I solve this? Its been at least 3 hours but still same.
