Secure email server policy
The goal of the policy is to allow .POST to be used for e-mail, while minimizing spam, phishing and other abusive e-mail.
14.02.2020This policy provides e-mail server authentication rules for establishing e-mail servers under .POST, using the Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM) and Domain-Based Message Authentication, Reporting and Conformance (DMARC).
14.02.2020Transport Layer Security (TLS) is an open standard for encryption which enables people and applications to communicate in private over the Internet. TLS is the successor to Secure Sockets Layer (SSL) technology, and it provides three essential services to help ensure security on the Internet:
1. Message confidentiality, 2. Authentication, 3. Message integrity
No redirection of .POST domains should be allowed (to avoid misuse and hijacking). An alternative to redirection is to give the domain the status of a parked domain and remove unnecessary A records on the DNS for the redirection of the domain.
