E-mail
E-mail is one of the most popular features of the Internet.
E-mail allows you to send and receive messages instantaneously to
anyone on the Internet. Additionally, e-mail allows you to send
files as attachments to messages. E-mail is the electronic equivalent
of postal mail, only much faster.
About Clients
As with everything else on the Internet, there are
many different programs that you can use to access e-mail. Many
of the latest web browser packages come complete with an e-mail
reader built into them. However, some people prefer other programs,
such as Eudora, Pegasus Mail, or Claris E-mail. These programs normally
come with more features than most of the web based mail readers.
Of the many different e-mail programs available, most
share the same basic features. These features include the ability
to send and receive, save, and include attachments.
Getting E-mail
Once the e-mail software is setup, sending and receiving
is done without much effort from the user. Most mail programs will
check for mail when you first open the program up. You can also
set the mail programs to check for mail at regular intervals. This
is convenient if you are logged on for extended periods of time
using the system and would like to be notified when you receive
mail without actively looking for it.
Sending mail, much like receiving mail, is done automatically
in most cases. Once you have completed your message and clicked
the send button, the mail is instantaneously sent. Some mail programs,
such as Microsoft Internet Mail, will queue the mail, or place it
into a holding bin until the next mail run is initiated. A user
can have the mail server check for new mail at regular intervals
in an automated process, or by clicking the designated button for
receiving and sending messages.
Addresses
Everyone who has access to the Internet has an e-mail
address. E-mail addresses are similar to postal mailing addresses,
in that they include a name and a location. However, unlike postal
mailing addresses, if you do not enter the e-mail address in exactly
as it should be, the mail will not be delivered. E-mail addresses
are also case sensitive, so be sure that if the e-mail address is
in all upper or lower case, it is typed in exactly as it appears.
An e-mail address consists of a username and a domain,
or location where that user resides. For instance, if you were to
e-mail our support staff here at ETI, the address would look like
the following:
support@eticomm.net
That is read support at eticomm.net.
Support is the username. The '@' ,or 'at' sign, then tells the mail
program that the rest of this address is where the username resides.
Eticomm.net is the actual domain, or address on the Internet where
all of ETI's users reside.
E-mail Attachments
Most e-mail programs today provide the ability to send
and receive attachments. An attachment is simply a file or text
document that can be attached to an e-mail message. This is very
useful if you need to send one or more small files to someone. It
makes sending and receiving files over the Internet very easy.
Because the Internet e-mail system was originally designed
for sending text-only messages, sending attachments can sometimes
be difficult. When a file is attached to an e-mail, the file itself
has to be encoded in one of many encoding formats. The three most
popular attachment formats MIME, UUEncoding, and Base64
are supported by most of the popular mail clients. On the user end,
you do not have to worry about the type of encoding, as this is
done automatically through the mail program. The only time users
need to know about encoding is when they receive a message that
their mail program can not decode. In this case, the easiest thing
to do is to write back to the sender explaining that your program
could not decode the document.
Another downfall to a text based mail system is the
file size. Because the e-mail system was originally designed for
text only it does not handle large files very well. You cannot send
out a file larger than 2 megabytes through ETI. So, if you're sending
an attachment, and you receive an error, check the size of the file
you are sending to be sure it is not too large. Remember that the
total size of the e-mail message is based upon both the size of
the actual message, as well as the size of its attachment.
