But what if you are hosting one server as email server for multiple domain? I cannot put multiple domain into 1 ip. What to do this case?
Hi, I have the same problem. Did you find a solution ? Thanks
You only need to choose one hostname for your mail server (e.g. mail.domain1.com) and as long as the PTR record matches the hostname you should be fine, even if you’re hosting more domains on it.
Hello,
The name of the droplet must have a FQDN format name. In this way the assigned PTR record will be correct and you wont have issues with it.
DigitalOcean automatically configures the reverse dns entry (PTR) on their end. It will be the hostname you choose when you set up your dropplet. You can change/check this in the control panel by selecting your dropplet, then settings, then rename. As it says, changing the name there will update the PTR but not the hostname of the system, that is something you will need to do, instructions for that vary depending on the system you have installed.
Hope this helps! Let me know if you have any questions.
Regards,
Alex
