MX servers are accessibles

Passed

Smtp servers that are listed in DNS area must be accessible, otherwise, there is a risk that emails may be lost

0.000s

MX IPs have reverse

Passed

When a sending server makes a connection to the recipient server, the recipient server notes the sending IP address and performs a reverse lookup, called a PTR lookup, named after the type of DNS record used. If the result of the reverse lookup matches the result of a forward DNS Lookup, then it's much more likely that the message is legitimate. If the IP address doesn't match, it's much more likely that the sending address was spoofed and therefore much more likely that it's unwanted and could be considered spam.
