Hi,
i only want to add some hostnames for mail setup like pop3, smtp
so i added to dns zone template this new record:

..................................
..................................
%domain%. IN A %ip%
%domain%. IN AAAA %ipv6%
ipv6 IN AAAA %ipv6%
%domain%. IN MX 0 %domain%.
mail IN CNAME %maildomain%.
pop3 IN CNAME %maildomain%.
smtp IN CNAME %maildomain%.
www IN CNAME %domain%.
ftp IN CNAME %domain%.

after changes i reset my zone but hostnames does not work and dns does not resolve

# dig @host.example.com smtp.example.com A

; <<>> DiG 9.11.4-P2-RedHat-9.11.4-26.P2.el7_9.10 <<>> @host.example.com smtp.example.com

Hey there! Can you confirm that the DNS zone reset did indeed increment the serial number and also add the records you are expecting? If so, can you try that "dig" command again without the "A" at the end? Since you're using a CNAME the "A" could be causing confusion with that lookup.
