You are responsible for the e-mail that you send out and can be held accountable for outgoing mail both legally and ethically. At any rate, e-mail is easily forwarded, so don't say anything that you wouldn't want repeated. Besides this, your e-mail usage is expected to obey computer usage terms. This means that using your e-mail account to forward offensive jokes and materials can result in your computer privileges being revoked. What one may consider a joke may be considered as harassment by another.
Most states permit such actions to be files in small claims court.
Be considerate with your content Include a subject line for your e-mail that identifies what the content of your message is. Doing this helps the receiver sort through his or her e-mail easier, and refer to the message quicker. Additionally, try to stick to one subject per message. Jumping around can become confusing and hard to follow. Try to keep your messages short and to the point.
