Hello, it is recommended that you check the logs of the mail server to see the specific information and what is the cause.
Check the mail score and troubleshoot according to its error message

Here are errors:
Your IP address xx.xx.xxx.xxxx is associated with the domain mail.xyz.com.
Nevertheless your message appears to be sent from localhost.localdomain.
and no A records for localhost.localdomain

in my PTR, i have for IPv4 set up like
My Ipv4 + mail.xyz.com

Ipv6 + mail.xyz.com

I dont know where is localhost.localdomain from

It is recommended that you check the log of the corresponding mailbox, which should be the operating system user's
Also check the postfix configuration
