Zpanel Not Sending Mail Problem
Sorry my english is not good. I installed zpanel on CentOS 6.5 x64. However, I can not send mail and Thunderbird Mail settings can not. When I studied the problem and came across something like this. When questioned at http://www.intodns.com/nailuzun.co gave the following error. "ERROR: No reverse DNS (PTR) entries. The problem MX records are: 18.104.22.168.-addr.arpa -> no reverse (PTR) detected You should contact your ISP and ask him to add a PTR record for your ips " What should I do? Thank you.
