E-mail Protocol

The protocol is a software that is a group of all the rules that are used to transfer data from one location to another. Protocols are different types and are used according to the needs and requirements. Email is a facility that is used to send mails via computer using internet. The protocols that are used for emails are known as Email protocols. The most common type of Email protocols are:
SMTP: – The SMTP (Simple Mail Transfer Protocol) protocol is used by the Mail Transfer Agent (MTA) to deliver your Email to the recipient mail server. The SMTP protocol can only be used to send emails, not to receive them. This protocol is a member of TCP/IP Protocol. ASCII character set is used in SMTP Email protocol.
X.400: – X.400 is the Message HHHhhhhggghandling Service Protocol for email transmission is specified by the ITU-T and ISO. X.400 is a common in Europe and Canada and is an alternative to the more popular email protocol, Simple Mail Transfer Protocol (SMTP) which is defined by IETF. X.400 used a binary format so it is easy to include binary contents without encoding it for transfer. Also, it is a harder for people to fake email addresses and contents than with SMTP, where text messages are used.
UUCP: – Unix to Unix Copy this protocol is the mainly used on UNIX operating system. This protocol help in transferring files from one host to another host in Unix operating system.
POP: – the POP (Post Office Protocol) provides a simple, standardized way for users to access mailboxes and download messages to their computers. When using the POP protocol all your email messages will be downloaded from the mail server to your local computer. You can choose to leave copies of your emails on the server as well. The advantage is that once your messages are downloaded you can cut the internet connection and read your email at your leisure without incurring further communication costs.
MIME: – Multipurpose Internet Mail Extensions specifies how messages must be formatted so that they can be exchanged between different email systems. MIME is a very flexible format permitting one to include virtually any type of a file or document in an email message. MIME messages can contain text, images, audio, videos, or other application-specific data.
IMAP4: – Internet Message Access Protocol version 4 is the current version of IMAP, a method of accessing electronic mail or bulletin board messages that are kept on a mail server. IMAP permits a “client” email program to access remote message stores as if they were local. Email Stored on an IMAP server can be manipulated from a desktop computer remotely, without the need to transfer messages or files back and forth between these computers. The key feature of IMAP4 includes: fully is compatible with Internet messaging standard e.g. IMAP. It allows message access and management from more than one computer. It also allows access without reliance on less efficient file success access protocols. Provides support for “online”, “offline” and “disconnected” access mode. Supports concurrent access to shared mailboxes client software needs no knowledge about the server’s file Store format.
