When accessing the Email Deliverability section within cpanel, you may see a variation of the message "Error: “HASH(0x2e5f600)” is not a valid IP address" and no domains are displayed.
The error appears in the cPanel interface when looking at the Email Deliverability user section. This will show a variation of the following message where the hash may differ:
Error: “HASH(0x2e5f600)” is not a valid IP address
This usually happens when custom modifications have taken place to the users cPanel file.
For the user in question, verify if there is an additional domain or a duplicate of the primary domain in the
/var/cpanel/users/username file on the DNS= line. If there is you'll want to open the users file with your favorite editor, vi/vim/nano and modify the DNS= section to remove the duplicate entry. Run the
updateuserdomains script and that should handle the error in the interface.
# nano /var/cpanel/users/user_in_question
# diff -u /var/cpanel/users/user_in_question /root/cptechs/user_in_question
