Domain name analysis
ALTOSPAM’s website https://www.altospam.com/outil/ offers a tool for analyzing the integrity of a domain’s mail service configuration.
First of all, this tool checks that the naming in the 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 on 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.
