Explanation

MIME (Multipurpose Internet Mail Extensions) is the standard binary encoding format used for email. It allows non-ASCII content such as attachments, images, and binary files to be transmitted over email protocols. SMTP and IMAP are email protocols (for sending and retrieving mail, respectively), not binary coding schemes. Uuencode is an older binary-to-text encoding method that predates MIME and is rarely used today. MIME is the universally adopted standard for encoding email content.
