Domain name and mail server analysis tool
This tool can be used to analyze the integrity of a domain’s mail service configuration.
First, it checks that the naming in Whois is consistent with the naming specified in the DNS NS fields.
It then contacts all the DNS associated with the domain and checks the presence and correspondence of the MX fields specified in each DNS.
Finally, it contacts the registered mail servers and extracts the welcome header. If you have specified an email address, the script continues by simulating the sending of an email to the main mail server detected.
The analysis may take several seconds, so please be patient.
