Hello, I am new to digitalocean. I find the service just great. I could set up a my first vps really quick and configure it in a relative short time following the tutorials. I am now struggeling a little to configure the server to receive and send emails though. In concrete, I want to associate the domain with the preexisting mail server provided by the registrar. In this case it is IceWarp, but might be any other, according for instance to the needs of a client. I have tried to enter the MX and CNAME records so far, but it won't work. Moreover, I can't telnet my port 25. I am wondering if anybody here went trhough this issue already, and could successfully associate domain and email server...
