hello
resolver configuration sometimes resets
as in the attached picture.

when this happens
emails sent to us do not arrive with a sender verify failed error.

this problem occurs every 2-3 months.
i think after updates.

how can i solve this problem.

can i solve this by making the resolv.conf file unchangeable?
chattr +i /etc/resolv.conf

OS : AlmaLinux v8.10.0

i am waiting for your help on this issue
THANKS.

regards

  Hey there!  In general, I wouldn't expect the resolv.conf file to change on a server after it has been written.  I'm not aware of any automated methods within cPanel that would perform that work.

  You should absolutely be able to chattr the file with no ill effects.

  if your server is using DHCP it may change /etc/resolv.conf
