Lookup Types

Command Explanation
DMARC: Lookup your domain’s DMARC record by selecting “DMARC” from the menu or typing “dmarc: domain.com” in the search box
SPF: Lookup your domain’s SPF record by selecting “SPF” from the menu or typing “spf: domain.com” in the search box
DKIM: DKIM (DomainKeys Identified Mail) allows senders to associate a domain name with an email message, thus vouching for its authenticity. This is done by "signing" the email with a digital signature, a field that is added to the message's header. The recipient MTA can verify the DKIM signature, which gives users some security knowing that the email did actually originate from the listed domain, and that it has not been modified since it was sent.
BIMI: BIMI, or Brand Indicators for Message Identification, is a new standard created to make it easier to get your logo displayed next to your message in the inbox. Not only will this help your visibility, but BIMI is designed to prevent fraudulent emails and aid deliverability, too.
MTA-STS/TLS-RPT: Lookup your domain’s MTA-STS and TLS-RPT records by selecting MTA-STS/TLS-RPT from the menu or typing “mta-sts: domain.com” in the search box
Blacklisting: Find your IP addresse’s blacklisting information by selecting “Blacklist” from the menu or typing “blacklist: 1.1.1.1” in the search box
Whois: Find your domain or IP address WHOIS information by selecting “whois” from the menu or typing “whois: 1.1.1.1 or domain.com” in the search box
PTR: Lookup your IP address PTR DNS record by selecting “PTR” from the menu or typing “PTR: 1.1.1.1” in the search box
NS: Lookup your domain’s NS DNS records by selecting “NS” from the menu or typing “ns: domain.com” in the search box
MX: Lookup your domain’s MX DNS records by selecting “MX” from the menu or typing “mx: domain.com” in the search box
FCRDNS: Perform an FCrDNS check on your IP address by selecting “FCrDNS” from the menu or typing “fcrdns: 1.1.1.1” in the search box
