Sending and receiving mail

The Simple Mail Transfer Protocol (SMTP) is a TCP⁄IP application that is used to transport electronic mail. Electronic mail enables you to send notes, messages, letters, or correspondence to others on the network. It is similar to sending a letter through the post office. You compose the message just as you would an ordinary letter, address the letter to one or more people and possibly carbon copy others. You enclose copies of the letter in envelopes, address them to the recipients, and give them to the delivery system. You expect the mail to be delivered to the correct address available for pickup when the recipient is ready. And you want any undeliverable mail returned to you. You can even keep a log of the mail you send and receive. The following commands are available to let you send and receive mail:

Command	Description
SMTPNOTE	Composes and sends mail from you to users on local or remote hosts. The TSO SMTPNOTE command helps you address the mail, set up a copy list, and enter the text of the message. The date, time, and your address are included automatically.
z/OS UNIX sendmail	Composes and sends mail from you to users on local or remote hosts. The z/OS UNIX sendmail command helps you address the mail, set up a copy list, and enter the text of the message. The date, time, and your address are included automatically.
RECEIVE	Retrieves data that has been sent to you through the Job Entry Subsystem (JES). You use the RECEIVE command for your TCP⁄IP mail just as you do for other mail, messages, and data sets that are sent to you.
