Introduction to Email
Today's lesson will be a general discussion of electronic mail (or email for short. Note that the hyphen [as in "e-mail"] is usually not used any longer). In this lesson I will explain email addresses, teach you how to send email, and show you how to find email addresses for folks you wish to contact. Electronic mail is a major component of the Internet and can be used to participate in nearly every available online activity. Beyond its pure Internet use, you may find that email can replace other forms of communication for you. It's faster than the U.S. Mail (or snail mail, as it's called on the Net) yet has all the positive factors of a written note. Unlike faxes or phone calls, you can't get tied up with a busy signal or an answering machine. Your message goes through and can be read by its receiver in its full length prose form. Of course, the email reading habits of the person you're emailing makes a huge difference in how quickly they receive the message.
What the Heck is a Domain, or What Does this Address Mean?
You should now have an Internet email address. For those of you who don't know your full address (past your username), here's my full email address:
erickson@mail.augsburg.edu
(Note: Currently, most Augsburg email addresses leave out the "mail" part of the address. For the purposes of this lesson, we will leave it in order to discuss its function).
The first part, "erickson," is my login. This is the public name by which I am identified on the Internet. A login (also called a user name or user ID) can be any combination of letters and/or numbers, but in my case, it is pretty straight forward--it is my last name. Many folks at larger organizations (such as the U. of Minn.) get logins such as "eric0001" and "spectre" (a nickname) since too many people possess similar real names (there are literally hundreds of Johnsons at the U. of Minn.).
What about the rest? The "@" means "at." as in "erickson is at... ." That's pretty easy to understand. But what does this gobbledygook after the "@" mean? It's called a domain name, and this one is composed of three subdomains. Let's take it bit by bit, from right to left:
"edu" tells us that this account is at an educational institution.
"augsburg" is the name of the institution where the computer is located.
"mail" is the name of the computer on which my email account resides.
More often than not, at least with educational institutions, the institution domain will be an abbreviation of an actual college or university. Let me show you a few more examples before explaining the individual domains a bit more.
There will not always be only three subdomains in an address. While this is most common, two, four, or five subdomain addresses show up quite a bit.
mason@utkvx.utcc.utk.edu
This address tells us we're sending to a person at an educational institution, which is the University of Tennessee at Knoxville, who is attached to the University of Tennessee Computing Center, and who's account is on a computer called utkvx (a VAX computer). The extra subdomain here tells us what specific area of the university this person works in or has an account through.
fred@aol.com
This address tells us that this person has a commercial account, provided by the vendor America Online. It's more common to see two subdomains in commercial account. You're bound to see more and more people with this domain name since American Online is the world's largest ISP.
Now let's talk about these three-letter, also known as top-level, domains. The following list contains domains that are commonly used in the United States. I'll cover other countries in a moment. Alphabetically, the top-level domains are:
com - commercial organization
edu - educational institution
gov - government agency
int - international organization
mil - military group or agency
net - networking organization
org - nonprofit organization
Just knowing these domains will let you identify immediately what sort of account a person has and perhaps what their position is within an institution or organization.
Things do get trickier on an international level. Each country in the world has been assigned a two-letter country code to use in their domain names. What countries will do is place this two-letter subdomain farthest to the right. Then they may add a subdomain which tells you what type of institution is represented (much like the U.S. top-level domains). Let me give you an example.
carlos@compsci.ox.ac.uk is the address of a person in the Computer Science department at Oxford University ("ac" stands for academic, "uk" is the country code for the United Kingdom).
Use of the institution type subdomain varies from country to country, but especially in Europe "ac" is used to denote academic sites. It can be fun trying to work out where a person is located when you see their email address on a listserv. After a while it becomes second-nature.
For many years, U.S. Internet addresses did not make use of the country code, but as more sites form it is becoming more standard. Particularly in the case of freenets (community-based, cooperative, often free network providers), a domain name that includes the country code is common. State names are usually included as another subdomain. In Minnesota, for example, addresses on a local freenet might look like this:
erickson@vax.freenet.mn.us
There will be more domains in the near future because the Internet is already running out of names! These new domains will have abbreviations like ".corp" and ".med," and ".biz," so look for these in the not-so-distant future.
Setting Up an Email Account
Starting in the Fall of 1999, the college initiated Augsburg AugNet WebMail. Since most new users prefer this web-based alternative, we will focus on WebMail in this course. Traditional email programs such as Eudora and Outlook will continue to work--WebMail is just an alternate way to interact with our email sysrem.
In order to access AugNet WebMail, you need an email account and password. These are obtained from the Augsburg IT Department on the second floor of the Lindell Library. Please get an account if you do not already have one. In additional to receiving Augsburg email, the login and password will grant you access to AugNet, the college's intranet, and other password-protected college resources. It is also possible to obtain an AugNet username and password without setting up an email account, but of course you won't get AugNet WebMail without an Augsburg email account.
If you already have an external web-based email account, you may be able to consolodate your email accounts into one by forwarding your other account to your Augsburg account. Check your external account to see if this is an available option. Then you'll only have to check for your mail at one place. Keep your other account for the day when you (sniff, sniff, sigh_:-( _) leave Augsburg.
Sending, Receiving, Forwarding and Replying
In order to begin your WebMail session, you need to start your web browser and type in either of the following URLs: <http://webmail.augsburg.edu/>. <http://www.augsburg.edu/augnet/webmail/>. The following web page will be loaded:
In the appropriate fields, type in your username (also called a login or User ID) and password exactly as they appear on your email account agreement. Then click "Log In" (or hit the [Return] key). This will take you to WebMail's "New Mail" Folder.
By default, WebMail will check to see if you have any new email.
Unread messages will be bold, and will have a 
icon in the "status" column. Messages you've seen before will be in
normal text and will have a 
icon in the first column. You can check for new messages (messages
that may have arrived since you started WebMail) by clicking on the
"Check" button.
In order to file or delete an item, first select the message by clicking in the checkbox next to that item's subject. Then click the button from the top row which corresponds to your intended task.
To open a message, click on the hyperlink under the subject heading. Your open message will appear in a new window.
When you open a message, more buttons will appear which include options such as reply and forward. Ciick the button which corresponds to your intended task.You will need to address forwarded messges. Simple reply messages are automatically addressed to the sender of the current message.
New messages can be started by clicking on the "Create" button.
You may send copies to other parties by including their email addresses in the "To," "Cc," or "Bcc" lines, depending on whether you want the person to be a first recipient, to only receive a copy, or to receive a "blind" copy, which means the other recipients won't know who the "blind" recipient is. The "Bcc" is helpful in certain confidential situations.
Attachments
Attachments (other computer files such as pictures or word processing documents) can be affixed to your outgoing mail by selecting the "Attach" button. A new window appears which displays a "Browse... " or "Select..." button. Click the button--this will return a dialogue box like the one below. Use this dialogue box to navigate to the file you want to attach. Double-click on the file's name (the picture file "fenway park.gif" in this example) to designate the file for attachment. The file's name will appear in the box titled "Filename." Click "OK" when you're done adding attachments. When you send this email message, the attached file(s) will also be sent.
Be forwarned: Attachments often don't work if the intended recipient doesn't have the appropriate software to read the attachment. Good email ettiquette suggests you clearly indicate to your correspondent with what program they can open your attachment. For example, in the illustration above I might say to my correspondent, "use your web browser to view this picture of Fenway Park." Remember: if they don't have the right software, they won't be able to open the attachment.
An article describing in greater detail the issues involved in email attachment problems can be found at this link. While this page has much useful information, it is fairly technical. As a result, it is not included in the "official" lesson on email. Read it if you want some extra in-depth disussion of this topic.
Finding Email Addresses at Augsburg
All right, now you can capably send email across the globe. To whom will you send it? Better yet, how can you find someone out there and get their email address? No problem, I say. Let's talk about a few situations.
First, you want to know the email address for someone on campus. The college maintains an online web-based directory. You must have an Augsburg AugNet account (username and password) in order to access the Augsburg directory page. To get to this page you will be asked to provide your username and password in order to proceed.
The directory address is: http://augnet.augsburg.edu/. Once at the AugNet page, click on the word "directory" which is in the blue banner.
It is very easy to use--just type in the name of the person whom you're seeking.
You can click on the highlighted address (above) to go directly to the directory. Remember to come back to this page (hit the [BACK] button on your browser) to continue the lesson.
Finding Email Addresses Away From Augsburg
Next, you'd like to know the email address for someone in the world beyond Augsburg. This is an uneven, but not impossible, quest. At this time, there is no single "White Pages" guide to all email addresses, even though there are web sites that call themselves the White Pages. There are many ways to find addresses, but none promise complete success. It is easiest to find a person's address if you know where a person is. I'll mention a few methods of doing this, and if you have questions about other methods, please let me know.
There are many phonebooks available on the Internet. Some are available via the web sites for major institutions such as schools and corporations. Your task is to find the web site of the institution at which your intended correspondent resides, then find the link on their web site to their email directory. This usually promises the best results.
Many other phonebooks are available via the World Wide Web (see
the partial list that follows). There are many more than the few
listed here. You can search these phonebooks using a web browser.
Follow the instructions which are available when you log onto the
various sites.The general-purpose sites listed here are a
hit-and-miss proposition. Unless you know a person is affiliated with
a particular web site (for example, s/he has registered themselves
with a particular directory) you will probably be disappointed.

Adding Signatures To Your Email (and Other Options)
If you got unsigned mail with no return address, wouldn't it make you feel a little uncomfortable? Well, that's just what you might be doing if your email doesn't have a signature. An email signature is a small piece of text which is appended to outgoing email messages. In WebMail it is accessed via the "Change Options" dialogue box. To bring up this box, click on the button labeled "Options."
Type your full name in the "Full Name" box. You may use upper and lower case. Then type your electronic signature in the "Message Signature" box. It should include the information people need to clearly identify you, but probably should not include things like your home address and phone number. Some people add favorite quotes and other personalizations to their signature, but be careful--signatures which are too informal may reflect poorly on you when you seek employment or conduct other serious correspondence.
As you can see, several other options are also accessed via this dialogue box, including message handling details and a choice of the template or theme displayed by WebMail when you log in. Change the template to some others and see which one suits you best.
Conclusion
Well, I have given you a lot of information in a single lesson. The remaining lessons will not be this large (nor will they continue to grow in size!). Upon completing this lesson, you should be able to send mail to anyone, anywhere, providing that you have their address. You should also understand several methods of finding a person's email address. Below are a few assignments which will allow you to practice your new skills. The only way to get good at this is to practice. Don't worry--you can't break the computer! Experiment, enjoy, and don't be afraid to ask questions along the way.
