RFC 5293 – Editheader; allows a script to add and delete message header fields. RFC 5429 – Reject; allows messages to be rejected at either the LMTP/SMTP level or with an MDN or DSN. RFC 5435 – Notifications; allows a script to trigger external notifications of email.
Clicking on the hyperlink automatically opens the default email client, with the destination email address pre-filled. It is possible to specify initial values for headers (e.g. subject, cc, etc.) and message body in the URL. Blanks, carriage returns, and linefeeds cannot be directly embedded but must be percent-encoded: [4]
Message-ID is a unique identifier for a digital message, most commonly a globally unique identifier used in email and Usenet newsgroups. [1] Message-IDs are required to have a specific format which is a subset of an email address [2] and be globally unique. No two different messages must ever have the same Message-ID.
RFC 5322 specifies the syntax of the email header. Each email message has a header (the "header section" of the message, according to the specification), comprising a number of fields ("header fields"). Each field has a name ("field name" or "header field name"), followed by the separator character ":", and a value ("field body" or "header ...
It is specified in a series of requests for comments: RFC 2045, RFC 2046, RFC 2047, RFC 4288, RFC 4289 and RFC 2049. The integration with SMTP email is specified in RFC 1521 and RFC 1522 . Although the MIME formalism was designed mainly for SMTP, its content types are also important in other communication protocols .
This allows a receiving service to validate an email when the email's SPF and DKIM records are rendered invalid by an intermediate server's processing. [1] ARC is defined in RFC 8617, published in July 2019, as "Experimental". [2]
To use Unicode in the domain part of email addresses, IDNA encoding must traditionally be used. Alternatively, SMTPUTF8 [3] allows the use of UTF-8 encoding in email addresses (both in a local part and in domain name) as well as in a mail header section. Various standards had been created to retrofit the handling of non-ASCII data to the ...
Header Identifies which algorithm is used to generate the signature. In the below example, HS256 indicates that this token is signed using HMAC-SHA256. Typical cryptographic algorithms used are HMAC with SHA-256 (HS256) and RSA signature with SHA-256 (RS256). JWA (JSON Web Algorithms) RFC 7518 introduces many more for both authentication and ...
