Electronic Mail

1. The name of the system you are using is usually found by issuing the command

   hostname

2. To send yourself some mail, simply use the mail command such as

   mail my_logon

   and fill up the subject line (if any). Write a line or two, then enter a dot (.) on a line by itself to finish the main body of the letter.

   You may then see a Cc:. The system is asking if you want to send a complimentary copy to someone else. Press the return key, and mail will be sent.

3. To send someone else a message, follow the same procedure as outlined above, but use their logon name for my_logon.
4. Assume the remote user is cantin and that his FULL system name is nrccsb3.di.nrc.ca. To send him mail,

   mail cantin@nrccsb3.di.nrc.ca

   is used, and the same procedure outlined above follows.

   BUT: your system has to be configured to use mail. If it is not, contact the Networks Branch of Informatics Services (993-0240), and ask to talk to the person in charge of UNIX in the Networks Branch. Ask that person how to install sendmail.

5. When writing a message, a file can be inserted using

   ~ r filename

   on a line by itself (that is ``tilde"-r filename).
6. If the message to be sent is already in a file (let's call it message), and my user name is cantin, I can send myself that file via mail using

   mail -s "Subject of this Message" cantin < message

7. Mail can be read using

   mail

   When reading mail, the current letter can be saved in the folder folder by issuing the s +folder command. The plus sign (+) means that the following file is to be a folder.

   To reply to yourself, simply enter

   r

   at the mail command line.
8. Any outgoing mail is saved in a file called .record in your own $HOME/mail directory. To send the mail to your friend, use the mail command to read the .record folder, save the message in a file by itself, and reply to your friend, using the content of the new file for the body of the message.

9. Issue elm to enter the package. From within the package, ``o" will bring the menu option. Issue ``u" to go to the user level menu, and press the space bar for your selection.

   Save your selection by pressing the larger-than (>) sign.

10. Re-enter elm. Issue ``a" to bring the aliases menu. Follow directions elm issues.
