Some non-IMAP mobile email systems may not return receipts at all.Microsoft Outlook cannot show whether an email has been received or opened by the recipient unless you request a read receipt before sending the email. For example, you may get a read receipt if a person using an IMAP-based email client marks your message as read, but doesnt open it. How a receipt works depends on which email system your recipient uses. Getting a read receipt doesnt always mean the recipient read your message.

Government's ARPANET, standards were developed to permit exchange of messages between different operating systems. As more computers were interconnected, especially in the U.S. Users communicated using systems developed for specific mainframe computers. 6.7.2 SMTP MTA Strict Transport SecurityHistory Predecessors to SMTP Various forms of one-to-one electronic messaging were used in the 1960s.

SMTP became widely used in the early 1980s. In November 1981, Postel published RFC 788 'Simple Mail Transfer Protocol'.The SMTP standard was developed around the same time as Usenet, a one-to-many communication network with some similarities. RFC 780 of May 1981 removed all references to FTP and allocated port 57 for TCP and UDP , an allocation that has since been removed by IANA. Development work continued throughout the 1970s, until the ARPANET transitioned into the modern Internet around 1980.In 1980, Jon Postel published RFC 772 which proposed the Mail Transfer Protocol as a replacement of the use of the File Transfer Protocol (FTP) for mail. Further implementations include FTP Mail and Mail Protocol, both from 1973. Fewer than 50 hosts were connected to the ARPANET at this time.

Sendmail, released with 4.1cBSD in 1982, soon after RFC 788 was published in November 1981, was one of the first mail transfer agents to implement SMTP. Though Usenet's newsgroups were still propagated with UUCP between servers, UUCP as a mail transport has virtually disappeared along with the ' bang paths' it used as message routing headers. Both used a store and forward mechanism and are examples of push technology. SMTP, on the other hand, works best when both the sending and receiving machines are connected to the network all the time.

The Internet Mail Consortium (IMC) reported that 55% of mail servers were open relays in 1998, but less than 1% in 2002. Due to absence of a proper authentication mechanism, by design every SMTP server was an open mail relay. The original SMTP protocol supported only unauthenticated unencrypted 7-bit ASCII text communications, susceptible to trivial man-in-the-middle attack, spoofing, and spamming, and requiring any binary data to be encoded to readable text before transmission.

Standards such as Multipurpose Internet Mail Extensions ( MIME) were developed to encode binary files for transfer through SMTP. This separation of relay and submission quickly became a foundation for modern email security practices.As this protocol started out purely ASCII text-based, it did not deal well with binary files, or characters in many non-English languages. As spam became more prevalent, it was also seen as a way to provide authorization for mail being sent out from an organization, as well as traceability.

An MDA saves messages in the relevant mailbox format. Per RFC 5321 section 2.1, each hop is a formal handoff of responsibility for the message, whereby the receiving server must either deliver the message or properly report the failure to do so.Once the final hop accepts the incoming message, it hands it to a mail delivery agent (MDA) for local delivery. A receiving SMTP server may be the ultimate destination, an intermediate 'relay' (that is, it stores and forwards the message) or a 'gateway' (that is, it may forward the message using some protocol other than SMTP). Based on the target host and other factors, the sending MTA selects a recipient server and connects to it to complete the mail exchange.Message transfer can occur in a single connection between two MTAs, or in a series of hops through intermediary systems. Each process is an MTA (an SMTP server) in its own right.The boundary MTA uses DNS to look up the MX (mail exchanger) record for the recipient's domain (the part of the email address on the right of The MX record contains the name of the target MTA.

An MDA may deliver messages directly to storage, or forward them over a network using SMTP or other protocol such as Local Mail Transfer Protocol (LMTP), a derivative of SMTP designed for this purpose.Once delivered to the local mail server, the mail is stored for batch retrieval by authenticated mail clients (MUAs).
