on past... i just add mailserver... and activate the related php extension.... any solution for this? i had no idea how to fix this... any email that i sent to for the test... fail to reach the destination.... and the log shown like that....

Dhanamerdeka Required for PTR records.

Have you installed SSL for the mail server?

jonhcarter when i try to install it.... they shown nothing... i mean... and then after this loading... nothing happen.... do you had the solution? also... if i using cloudflare... the problem still the same... nothing added to the ssl.... they didn't installed... but the popup for application certificate appear.... but after dissapear... nothing added on ssl....

Change Cloudflare SSL settings to Flexible & then generate the SSL with the first option file method. for the DNS method, you need to disable the Cloudflare proxy first in Cloudflare DNS settings.

jonhcarter yeah same... Cloudflare "Your SSL/TLS encryption mode is Flexible" and proxy status... dns only,,,, then i create ssl with manual resolution and cloudflare... it's ended same... after loading... nothing happen on my side... they just dissapear.... no ssl added or else.... any other solution?

Just for note... All port open (say the tech support of my vps) i hope i can get mail server working.... on past... i already use it and it's works everytime.... just now i had this problem

Look like you SSL running well now. Does your web and mail service using different server? You may WA me if need help, I'm at Jakarta, Kota Komputer 082111978168 😀

aaP_kotakomputer.ceo i mean... so i just copy and paste the ssl from web to the mailserver? login roundcube is on mail subdomain and the ssl i just paste it from parent domain? because the issue is the ssl doesn't even added after loading

Now i get " The IP address sending this message does not have a 550-5.7.25 PTR record setup" error the way i can fix the error on original post is port "25" filtered (the vps company) said it's open... but it's filtered when i tested with nmap it's said "filtered" so the vps company fix it and now it's solved.... but now... the new problem is, any email that i sent... never arrive... for gmail user it says bounced (host gmail-smtp-in.l.google.com[142.251.12.27] said: 550-5.7.25 [103.187.146.233] The IP address sending this message does not have a 550-5.7.25 PTR record setup, or the corresponding forward DNS entry does not 550-5.7.25 point to the sending IP.

Dhanamerdeka Hello, find a server provider or network provider to make a PTR record for your ip. What is your system like? debian11 has not yet adapted to the mail server

aaPanel_Kern i use centos so this need to be solved by the vps provider?

Can't send email

aaPanel_Kern

It is recommended to consult the VPS provider and check whether the configuration is effective and correct.
