I have an issue with rDNS/PTR in CWP.
When I go to Server Settings -> Change Hostname, or Email -> MailServer Manager, I receive the follow message:
Your Hostname is: srv1.mydomain.com and it resolves to IP: mydomain.com. 10.20.30.40 [Check Black List]
rDNS/PTR = FAILED, check with your hosting provider! FAILED [Check SenderBase]
(domain name and IP changed)
When I check my DNS records for mydomain.com (DNS Functions -> List DNS Zones -> [mydomain.com.db] Check Records), I get this result:
rDNS/PTR record check: SUCCESS
rDNS/PTR = srv1.mydomain.com
rDNS A record = 10.20.30.40 [Check SenderBase] [Check RBL]
The content of mydomain.com.db (domain name and ip changed):
; Panel %version%
; Zone file for mydomain.com
$TTL 14400
mydomain.com. 86400 IN SOA ns1.mydomain.com. user.email.com. (

mydomain.com. IN TXT "v=spf1 mx a"
_dmarc.mydomain.com. IN TXT "v=DMARC1; p=none; rua=mailto:webmaster@mydomain.com"
Finally, cat /etc/hostname results in:
srv1.mydomain.com
There are something wrong in my dns configuration?
