I read try http://en.wikipedia.org/wiki/Simple_Mail_Transfer_Protocol smtp server move email around until the email get to a server that accepts it a local. You read mail from the that server via POP or IMAP or because it has been delivered locally (mbox or maildir). pop is the older style system, you connect to the server and then take all your mail. imap lets you do the above, but also lets you leave the mail on the server - all in one place. to send mail you use a mail agent that let you create a mail message and enter it into the smtp network (via you smtp server). Because of spam, most (well configured) server do not allow relaying through them except for certain clients/hosts/networks. A > mail by connecting to the IMAP server.
