how to set up a mail server on my ubuntu droplet
hello support: I am in a transition of moving my web applications from another web hosting service to digital ocean.
They updated my DNS to map my site to the new ip address. But it seems that I need to set up a mail server before they can route it too, as quoted
“A record changes will affected the MX record as it is the CNAME of xyz.com which is pointed to server’s IP address. If A record is changed to another IP address, mail server will be changed to the same IP address too.
Please let us know if you also want to routed an email service to another provider.”
so my understanding is that I need to install mail server on my ubuntu droplet before I give them a go-ahead, is it correct? Then is there a tutorial about how to set up a mail server?
thanks a lot,
