Email Fundamentals
• Information for email:






username (whnuser)
password (random, #’s, $, change)
email address (dandy_2c@students.umm.ac.id)
POP server name (e.g. popmail.umm.ac.id)
SMTP server name (e.g. mail.umm.ac.id)

SMTP: simple mail transport protocol
POP: post office protocol

Pine vs. Webmail vs. Eudora
• Pine
– software and messages always reside on campus server
– subject to quotas
– accessible by telnet by direct network connection or dial-up

• WebMail like Hotmail or Geckomail
– requires web browser
– requires dial-up or DN connection
– SoftWare and messages reside on commercial server (where?!)

• Eudora
– requires dial-up or DN connection
– SW resides on your PC
– you can choose where each message resides; flexible

Using Email Responsibly
• How to stay out of trouble
– Do not use company email for personal use
– Do not give information you would not give by
phone or in a letter
– Open and send attachments with respect
– Never respond to junk email (spam)
– Never use email to harass or intimidate
– When using company’s email, never say anything
you wouldn’t want your boss to see
