What is MIME?

MIME (Multipurpose Internet Mail Extensions) is a standard for encoding and sending multimedia content, such as audio, video, and images, over the internet. It allows email clients to send and receive messages that include a variety of different content types, such as text, HTML, and attachments.

MIME uses a system of "content-type" headers to identify the type of content sent and specify how it should be handled. For example, a content-type header of "text/html" indicates that the message contains HTML code, while a content-type header of "image/jpeg" indicates that the message contains a JPEG image.

MIME is an important part of the email system, as it allows emails to include a wide range of different content types and to be sent and received by a variety of different email clients.
