  • If you already have an email account, what do you need to know to set it up on your computer?

  • How do you subscribe to an email list?

  • Example: finding and subscribing to

    [email protected]


Email34 l.jpg

    • Many, many others

  • These can all be used through browsers


Setting up an email client l.jpg

Setting Up an Email Client

  • What if you have an email account and want to set up an Email program (also known as a client)?

  • Common, popular Email programs:

    • Outlook

    • Outlook Express

    • Eudora

    • Mac OS X Mail

    • Netscape

    • Mozilla, Mozilla Thunderbird

    • Opera, Pegasus, Lotus Notes… others?


Setting up email cont l.jpg

Setting Up Email, cont.

  • These items will usually be supplied by your Internet Service Provider (ISP), but…

    What do they really mean?

    • Account Name

    • User Name

    • Password

    • Incoming Server Name

    • Incoming Server Type

    • Outgoing Server Name


Setting up email cont d l.jpg

Setting Up Email, cont’d

  • Let’s look at the easy ones first…

  • Account Name

    • This is going to be the full email address, and will look something like: [email protected], for example, [email protected]

  • User Name

    • This is just the part before the @, so in the example here, would just be anne

  • Password

    • This is whatever was assigned or chosen as a password when the email account was created.


Setting up email cont d38 l.jpg

Setting Up Email, cont’d

  • Now for the trickier ones… What’s a Server and what do these mean?

    • Incoming Server Name

    • Incoming Server Type

    • Outgoing Server Name


Setting up email cont d39 l.jpg

Setting Up Email, cont’d

  • Servers are computers that are set up to service requests. In overly-simplified terms, they are out there waiting for “clients” to ask them to do something. They typically hold on to large amounts of data, can search through the data, pass requests on to other servers, and talk to each other through well-defined rules called protocols.


Setting up email cont d40 l.jpg

Setting Up Email, cont’d

  • An email server typically uses a couple of different protocols, one called Simple Mail Transfer Protocol (SMTP), and one called Post Office Protocol (POP). SMTP is used by the email program on your computer to hand mail off to the email server. POP is used by the email program on your computer to retrieve your email from the server. Some servers use a different protocol called IMAP (the Internet Message Access Protocol), to retrieve your email from the server, but the information needed is exactly the same.


Setting up email cont d41 l.jpg

Setting Up Email, cont’d

  • Incoming Server Name

    • typically mail.domain.extension or pop.domain.extension

    • e.g. mail.registeredsite.com, pop.east.cox.net

  • Incoming Server Type

    • Usually POP3

    • IMAP more common on University/College systems

  • Outgoing Server Name

    • Typically mail.domain.extension or smtp.domain.extension

    • E.g. smtp.east.cox.net, smtp.idt.com, mail.madethisup.com


Subscribing to email lists l.jpg

Subscribing to Email Lists

  • What is an Email list?

    • Electronic mailing lists are a special usage of email that allows for widespread distribution of information to many Internet users. Software is installed on a server which processes incoming email messages and distributes the message to all users subscribed to the mailing list.


Subscribing to email lists cont d l.jpg

Subscribing to Email Lists, cont’d

  • Where to start looking:

    • www.yahoogroups.com

    • www.lsoft.com/catalist.html

    Internet safety l.jpg

    Internet Safety

    • Basics

    • What is Phishing?

    • What is Spoofing?

    • Avoiding Scams

    • Ways to avoid being Spoofed

    • More Spoofing

    • Virus Protection software

    • Email Attachments

    • Firewalls


    Internet safety50 l.jpg

    Internet Safety

    • Usernames & Passwords

      • When you register with different sites, you will generally pick a username and a password.

      • Write down the site name, username, and password and keep the information in a safe place (NOT on your computer).

      • Get in the habit of doing this each time you register with any site.

      • This way if something happens to your computer, you still have the information.

      • Protect your password information, since most people use the same password in a lot of places. If someone knows your password for one site, they might be able to use it to get at more personal information at another site.


    Internet safety51 l.jpg

    Internet Safety

    • Sharing Personal Information

      • Use caution in sharing personally identifying information in chat or on mailing lists. It is wise to choose an alias and not to tell too much about yourself until you are really sure that the person or persons you are conversing with are trustworthy. Trust your instincts.


    What is phishing l.jpg

    What is Phishing?

    • (fish´ing) (n.) The act of sending an e-mail to a user falsely claiming to be an established legitimate enterprise in an attempt to scam the user into surrendering private information that will be used for identity theft.

    • Phishing schemes often involve “spoofing” of internet addresses.


    What is spoofing l.jpg

    What is Spoofing?

    • In networking, the term is used to describe a variety of ways in which hardware and software can be fooled. IP spoofing involves trickery that makes a message appear as if it came from an authorized IP address.

    • Spoofing is used combined with phishing to email spam to thousand of people asking them to go to a web site to confirm some kind of confidential financial information

    • When they click on the link in the email, they arrive at a site that looks just like the business they expect, whether it is AOL, their bank, or some other institution they would trust with their credit card information.

    • Many people are tricked into entering personal data and credit card information on these sites.


    Avoiding scams l.jpg

    Avoiding Scams

    • NEVER enter personal data unless you are certain of where you are, how you got there, and if you are entering credit card or financial data, you should be on a secure web site (the URL should begin with https://)

    • The same goes for giving any personal information to someone who calls on the phone, even if they claim to be a representative of your credit card company checking to make sure your credit card hasn’t been used fraudulently. Hang up and call the number on the back of your credit card.


    Ways to avoid being spoofed l.jpg

    More spoofing spoofing and return addresses l.jpg

    More SpoofingSpoofing and return addresses

    • Spoofing also refers to forging an e-mailheader to make it appear as if it came from somewhere or someone other than the actual source.

    • It is possible for e-mail headers to be forged, just as it is possible for someone to forge a return address on a letter. Spammers do this all the time so that they are less likely to be caught.


    Virus protection software l.jpg

    Virus Protection Software

    • Anti-Virus software is absolutely essential for a PC running Microsoft Windows.

    • The ones with the most name recognition are the ones that come bundled with new PCs

      • McAfee

      • Norton Anti-virus

    • Free online scans for viruses and spyware are available at http://housecall.trendmicro.com. This site will test computer speed, 'net connection, drive health, etc. and not only flags any potential issues but also explains why the issue is important and how to address it.


    Virus protection software cont d l.jpg

    Virus Protection Software, cont’d

    • Free Anti-Virus software is available at http://free.grisoft.com. Click on “Get AVG Free” and follow the instructions to download and install the software.

    • Google keywords: virus protection


    Email attachments l.jpg

    Email Attachments

    • NEVER open an email attachments if you don’t know the person who sent it

    • Only open email attachments from someone you know if it has been scanned for viruses or it is a graphics (picture) file (.jpg, .gif).

    • Which email attachments are unsafe?

      • Any attachment that came from someone you don’t know

      • Almost any attachment except graphics (picture) files ending in .jpg, .gif that will simply be opened and displayed.

      • Attachments ending in .exe and .zip are particularly dangerous.


    Firewalls l.jpg

    Firewalls

    • A firewall is a security system that acts as a protective boundary between a network and the outside world.

    • Firewalls are a good idea if you have a connection that is “always on” such as a cable modem or DSL. With a connection that is always on, you may have the same address on the internet for long periods of time, and you have a high speed connection, making you a tempting target for a hacker.

    • If you are using a modem and dial-up connection, this is really not critical because it is unlikely that a hacker will try to get to your computer through a relatively slow dial-up connection that isn’t there all the time.

    • Also, when connecting to the internet through a modem, your address on the internet changes every time you connect.


    Firewalls continued l.jpg

    Firewalls, continued.

    • Windows XP includes Internet Connection Firewall (ICF) software you can use to restrict what information is communicated between the Internet and your home or small office network.

    • For information about firewalls, including places to get free firewall software go to:

      • www.zonelabs.com
