Nameserver software version   
One or more nameservers responded to version queries. This can be considered a breach of security. If a malicious person or program had access to a version-specific exploit for your DNS server, displaying the version info openly will make their attack much easier. This should be removed or obscured. The nameservers that responded to version queries are:

SOA field check   One
 or more SOA fields are outside recommended ranges. Values that are out of specifications could cause delays in record updates or unnecessary network traffic. The SOA fields out of range are:

expire | 604800 | EXPIRE - RFC1912 suggests a value between 1209600 to 2419200.

SMTP greeting   Malformed greeting or no A records found matching banner text for following servers, and banner is not an address literal. RFC5321 requires one or the other (should not be a CNAME). If this is not set correctly, some mail platforms will reject or delay mail from you, and can cause hard to diagnose issues with deliverability. Mailserver details:

114,444,444,555| WARNING: The hostname in the SMTP greeting does not match the reverse DNS (PTR) record for your mail server. This probably won't cause any harm, but may be a technical violation of RFC5321

Try change dns server in 'switch program' and then run 'sh /script/fixdns; sh /script/restart-dns'.

For warning (3), ask to your provider to set 'reverse-dns' for your IP(s).

Try running 'sh /script/fixdns; sh /script/restart-dns' from ssh.
