The SPF Surveyor is an SPF diagnostic tool that presents a graphical view of SPF records. The graphical view allows people to quickly identify which servers are authorized to send on behalf of a domain. (Note that this diagnostic tool focuses on domain-level authentication and largely ignores the portions of SPF that deal with the local parts of email addresses.)
he DKIM selector is specified in the DKIM-Signature header and indicates where the public key portion of the DKIM keypair exists in DNS.With the DKIM Inspector you can check if the public part of your DKIM signature—using the selector—has been implemented correctly in the DNS of your domain.
The implementation of DMARC starts with the publishing of a valid DMARC record. The dmarcian DMARC Record Checker is a diagnostic tool that allows you to view the DMARC record of any given domain and test if the TXT record is valid and published correctly.
This test will connect to a mail server via SMTP, perform a simple Open Relay Test and verify the server has a reverse DNS (PTR) record. It will also measure the response times for the mail server. If you don’t know your mail server’s address, start with a MX Lookup.
