To be a good network user and to protect yourself and others, follow these guidelines when sending electronic mail.
What to Do
Write carefully. Once you send an email message, you cannot take it back or make it disappear. The reality is that your messages may be saved for a very long time. They may also be read inadvertently by others, or forwarded to others without your knowledge.
Use upper and lowercase text. Using all uppercase letters means;
SHOUTING. SEE WHAT I MEAN?
Most people finding it annoying and harder to read.
This is also applicable to documents if necessary use bold font
Not underlining which indicate a hyperlink
Sign your messages with at least your name. It's nice to add your email address, too, since some email programs make it difficult to see who the sender of the message was.
Address your messages carefully. Some addresses may belong to a group, even though the address appears to belong to just one person.
Use the To, Cc, and Bcc fields (blind copy) correctly. Here are a couple of simple guidelines:
When sending to several people who know each other, it is okay to put their addresses in the To field.
When sending to many people who don't know each other, put their addresses in the Bcc field instead. (their e-mails are not shown)
Why? Addresses in the To field are visible to all recipients. Addresses in the Bcc field are not. Using the Bcc field means you're protecting the email addresses, not sharing them widely.
Indicate humour or jokes with a sideways smiley face, if you must not a British humour thank the USA for this oddity.
Be diplomatic. Criticism is always harsher when written, and email can be easily forwarded.
Be calm. You may have misunderstood what was meant. Don't reply while you're still angry (this is called "flaming").
Be brief. Do not include background images, pictures, animations, etc. unless they are critical to your message. When replying to a message, you do not have to include the entire text of the original message. Include just enough to give the context of your response.
Watch out for viruses and other threats in attached files. Attached files are a common way to spread computer viruses. Generally speaking, just receiving an attachment cannot infect your computer. But opening or running an attachment can. So if you are not sure Delete asp.
If you do not know why you got an attachment, contact the sender directly to verify that it is what it appears to be. Some viruses can attach themselves without the sender even knowing it; some can hide where they actually came from. It is also a good idea to scan all attachments with up-to-date antivirus software before opening them.
What Not to Do
Do not forward chain mail!
These messages tell you to send or forward them to several other people. Do not
Do not get fooled by Internet hoaxes and computer virus myths. Before you forward a so-called virus alert to everyone you know, check with the one of the web sites first see Google.
If in doubt consult your webmaster
