Reverse Entries for MX records

OK. All mail servers have reverse DNS entries configured correctly.

	Server	IP	PTR (Reverse)	IPs
	servermp.mpcfg.co.cu.	200.55.146.66	servermp.mpcfg.co.cu.	200.55.146.66

All mail servers should have a reverse DNS (PTR) entry for each IP address (RFC 1912). Missing reverse DNS entries will make many mail servers to reject your e-mails or mark them as SPAM.

All IP's reverse DNS entries should resolve back to IP address (IP → PTR → IP). Many mail servers are configured to reject e-mails from IPs with inconsistent reverse DNS configuration.

Check MX Records for Invalid Chars

OK. No invalid characters found. Name field from MX records should be a valid host name.

Check MX Records IPs are Public

OK. No private IPs found. Mail servers using private IPs can't be reached from the Internet causing mail delivery delays.

OK. No MX records duplicates (same IP addresses) found. Although technically valid, duplicate MX records have no benefits and can cause confusion.

Only Host Names in MX Records

OK. No IPs found in MX records. IP addresses are not allowed in MX records, only host names.

No CNAME in MX Records

OK. No CNAMEs found in MX records. RFC 2181, section 10.3 says that host name must map directly to one or more address record (A or AAAA) and must not point to any CNAME records. RFC 1034, section 3.6.2 says if a name appears in the right-hand side of RR (Resource Record) it should not appear in the left-hand name of CNAME RR, thus CNAME records should not be used with NS and MX records. Despite this restrictions, there are many working configuration using CNAME with NS and MX records.
