|“||It defines the standard ways of packaging one or more separate objects into a message so that any compliant mail system can use it. It specifies how to encode and encapsulate non-text attachments, such as voice and animation, to e-mail.||”|
Internet email was originally sent as plain text ASCII messages [RFC 2822]. The Multi-purpose Internet Mail Extensions (MIME) [RFC 2045] [RFC 2046] [RFC 2047] allows email to contain non-ASCII character sets as well as other non-text message components and attachments. Essentially MIME allows for an email message to be broken into parts, with each part identified by a content type. Typical content types include text/plain (for ASCII text), image/jpeg, text/html, etc. A mail message may contain multiple parts, which themselves may contain multiple parts, allowing MIME-formatted messages to be included as attachments in other MIME-formatted messages.
