1 1 Using email Messages sent from machine to machine and stored for later reading. You will use a client to read email: –Type mail or pine in UNIX to read email. –Use programs like Outlook on Windows. Different mail servers use the same protocols to communicate with each other.

2 2 Mail Servers SMTP (Simple Mail Transfer Protocol) transfers mail between servers. The mail server runs a program (daemon) that listens for clients connecting so people can read or write mail. On UNIX this program is called sendmail. A single protocol helps to ensure that different servers can communicate with each other.

3 3 Mail Clients POP -- Post Office Protocol –Downloads all mail at once. –IMAP -- Interactive Mail Access Protocol, adds features to POP Some Clients –ELM –PINE (PINE Is Not Elm) –Outlook –Eudora –Netscape Mailer

4 4 Parts of an Email Body -- This is the actual message. Header -- information at the top of the message. –From: or Received: who sent the mail. –To: Where the mail goes. –Cc: Other people who will receive this mail. Bcc: Blind carbon copy -- a list of people who get a copy of the message but don’t get listed. –Subject: What the mail is about. –Date: When the mail was sent.

5 5 The mail command You can use the mail command in several ways: –mail -- by itself, it opens your messages and lets you read them –mail person@address -- lets you compose a message to someone at a certain address. –mail -s (subject) person@address -- lets you send a message to someone at an address, with a certain subject. –mail -s (subject) person@address < text_file -- lets you send a message to someone with text_file as the body of the email.

6 6 Using mail When you are writing the mail message body, use ^D or. to end editing and send the message. If cc: shows up, this is a list of other addresses you can enter if you wish to send a message to other people. ^C will kill a mail message you are typing.

7 7 Mail commands These commands are used at the & prompt –q -- quit and save –x -- quit without making any changes. –R or r -- reply to a message (r = senders and recipients, R = senders only.) –f -- view the message headers. –p or t -- show those messages

8 8 More mail commands d -- delete messages. u -- undelete messages. s -- append the messages to with headers. w -- append messages to -- message only.

9 9 Message Editing Commands Use these while writing the actual message –~r -- Add a file into the message. –~f -- add another email into the message (forwarding). –~w -- write the message to a file. –~q -- quit without saving –~p -- print the contents of the message.

10 10 Header Editing While editing a message you may use… ~h -- lets you edit the header (to, subject, cc, bcc) These may also work: –~s -- edit the subject. –~t -- edit the to list. –~c -- edit the cc (carbon copy) list. –~b -- edit the bcc (blind carbon copy) list.

11 11 Other Features alias -- combine addresses -alias me johna@wam.umd.edu jra@math.umd.edu.forward file – send mailto another address. –Forward to self to get a copy on the sending machine. Listservs -- automatic mailing lists.

12 12 PINE A menu-driven client Uses pico as an editor Allows MIME attachments Main Menu –C - Compose to write a message –I or L - View messages –Q - Quit

13 13 MIME Attachments Multipurpose Internet Mail Extension Add pictures, files to emails Can be dangerous with executables. Pine uses MIME instead of plain inclusion. Filename on attachment line when writing.
