Use this website to check if your domain name's MX record points to the server's IP?
https://dnschecker.org/all-dns-records-of-domain.php
aaPanel_Kern It's weird, how it come pointing to another IP, not in my server IP?
aaP_johncharlie1272
Check the A record associated with the domain name
aaPanel_Kern Yep, it was associate to the rightful IP, which is my server IP, regardless I just re-install the mail server to give it a fresh restart. However the Postfix-install and Sqlite-support takes too much time to repair for operation. Is it normal? Tried several times but still not Ready its status. Same issue with this questions
aaP_johncharlie1272
What is your operating system? what version?
The A record used by the mail server cannot be an open proxy, and the resolved IP must be the IP of the server
aaPanel_Kern Here our operating system System: Debian GNU/Linux 11 x86_64(Py3.7.9) we dont have concern at A record yet, were having trouble in installing and uninstalling the mail server itself. Its very frustrating now. Can you help by checking it?
aaP_johncharlie1272
Hello, it is recommended to use ubuntu 20 or debian 10. Has debian 11 been adapted yet?
aaPanel_Kern But were always using Debian 10, for context, we already used the mail server for the last 2 years without having issues. Just now from last month we encountered issues, Id sent an email please check. TIA
