Email
RFCs
- RFC 5322 specifies the Internet Message Format (IMF), a syntax for text messages that are sent between computer users, within the framework of "electronic mail" messages. This specification is a revision of Request For Comments (RFC) 2822, which itself superseded Request For Comments (RFC) 822, "Standard for the Format of ARPA Internet Text Messages", updating it to reflect current practice and incorporating incremental changes that were specified in other RFCs.
- RFC 5321 Simple Mail Transfer Protocol (SMTP) Defines how mail servers communicate and transfer email messages.
- RFC 7208 Sender Policy Framework (SPF) Provides a method for verifying sender identity to prevent spoofing.
- RFC 6376 DomainKeys Identified Mail (DKIM) Allows the sender to sign messages, enabling recipients to verify authenticity.
