I have a dedicated web server based on cPanel. Recently I came across with some idea to set up my server with a transactional mail service, in potential Mailgun. There are many tutorials across the web explain how to integrate cPanel with Mailgun, something like this https://3sq.re/blog/2014/07/configure-exim-cpanel-use-mailgun/. However, I have been asking myself the following:
1) Is it better set up domain per domain or the whole server according to the tutorial above? 2) My server keeps receiving email, so we are going to have to platform dealing with email services? 3) What are the benefits and the drawbacks?
In addition, I have set up my server but just for test and it works.
I am not sure if I should keep this.
Thanks
