Chain mail is forbidden.
The exponentially increasing number of people who get a chain letter with each forward can give some mail systems pause. Likewise, try to limit the number of people to whom you send jokes or other mass-mailings. Repeatedly sending irate messages to someone doesn't accomplish anything, and in some cases may be considered harassment.
