SMTP (Simple Mail Transfer Protocol) is the standard protocol for sending and receiving emails between servers. It is used for transferring messages from a user's email client (such as Outlook or Gmail) to their email server (MTA). SMTP is also used by MTAs to send email messages from one server to another. MIME (Multipurpose Internet Mail Extensions) is a protocol used for encoding multimedia attachments in emails. IMAP (Internet Message Access Protocol) and POP3 (Post Office Protocol version 3) are protocols used for retrieving emails from an email server and delivering them to a user's email client. However, they are not used for transferring emails between MTAs.
