I had set up a small vps using cyberpanel, done configure the necessary setting include rdns.
unfortunately, when I send a test to mail-tester.com, I see this server.example.com, which I had no clue where to amend.
(I don't remember I had configured such URL during my installation 🤔)
Anyone can point me some direction?

when I try to issue ssl for my mail server, I receive this error message.
Cannot issue SSL. Error message: 0,283 Failed to obtain SSL for domain. [issueSSLForDomain]
Is there any additional step I require to take before I issue ssle for my mail server?
# wget -O - https://get.acme.sh | sh
After that I manage to add ssl for my mail server. I solve partially of the problem, but from mail-tester, I still see below error:
Your IP address 45.xx.xx.xx is associated with the domain server0.domain.asia.
Nevertheless your message appears to be sent from domain.asia.
You may want to publish a pointer (PTR type) DNS record with a value of
domain.asia or use server0.domain.asia as hostname in your mail software
Here are the tested values for this check:
IP: 45.xx.xx.xx
HELO: domain.asia
rDNS: server0.domain.asia
Basically my rnds is set in my vps control panel. I am no clue where should further troubleshoot?
Anyone can give me some direction? I believe I need to do some setting for PTR?
> I solve the problem by change my rdns from server0.domain.asia to domain.asia.
May I ask how you can do that?
