Hi,
the server uses Alma Linux 9, I deleted a user several times due to some problems and now we get to:
rDNS/PTR = FAILED, check with your hosting provider! FAILED
I have talked to my provider, this rDNS worked before when I used Centos 7, now at the beginning with AL 9, but when deleting and creating a new user it was lost?
What should I do?
Thanks in advance!

You need forward and reverse DNS, both agreeing in order to be considered a valid sending source for other servers to accept mail. It should not be tied to a particular user account. What is the server's FQDN?

If everything is correct then the RDNS of the primary IP assigned to your VPS/Server is good and there is no problem with the RDNS/PTR or... you missed something.
