Sender Policy Framework
A host's Sender Policy Framework (SPF) describes who can send mail on its behalf. This is done by publishing an SPF record containing a series of rules. Each rule consists of a qualifier followed by a specification of which domains to apply this qualifier to. For more information please see open-spf.org.
Warning: It appears that this host does not have an SPF record. There may be an SPF record on cboe.com: Check the site report.
Setting up an SPF record helps prevent the delivery of forged emails from your domain. Please note that an SPF record will only protect the domain it is added to and not any mail-enabled subdomains. It is recommended to add an SPF record to any subdomain with an MX record.
DMARC (Domain-based Message Authentication, Reporting and Conformance) is a mechanism for domain owners to indicate how mail purporting to originate from their domain should be authenticated. It builds on SPF and DKIM, providing a method to set policy and to give reporting of failures. For more information please see dmarc.org.
This host does not have a DMARC record. There may be a DMARC record on the site report for cboe.com: Check the site report.
