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.
| Qualifier | Mechanism | Argument |
|---|---|---|
| + (Pass) | ip4 | 93.186.224.0/20 |
| + (Pass) | ip4 | 87.240.128.0/18 |
| + (Pass) | ip4 | 95.142.192.0/21 |
| + (Pass) | mx | |
| + (Pass) | include | _spf.google.com |

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.
Raw DMARC record:
v=DMARC1; p=reject; sp=reject; pct=100; rua=mailto:postmaster@vk.com
| Tag | Field | Value |
|---|---|---|
| p=reject | Requested handling policy | Reject: emails that fail the DMARC mechanism check should be rejected. Rejection SHOULD occur during the SMTP transaction. |
| sp=reject | Requested handling policy for subdomains | Reject: emails that fail the DMARC mechanism check should be rejected. Rejection SHOULD occur during the SMTP transaction. |
| pct=100 | Sampling rate | 100% of messages from the Domain Owner's mail stream should have DMARC applied. |
| rua=mailto:postmaster@vk.com | Reporting URI(s) for aggregate data | postmaster@vk.com |
