答案

Electronic mail (abbreviated "e-mail" or,often,"email") is a store and forward method of composing,sending,storing,and receiving messages over electronic communication systems.The term "e-mail" (as a noun or verb) applies both to the Internet e-mail system based on the Simple Mail Transfer Protocol (SMTP) and to intranet systems allowing users within one organization to e-mail each other.Often these workgroup collaboration organizations may use the Internet protocols for internal e-mail service.E-mail is often used to deliver bulk unwanted messages,or "spam",but filter programs exist which can automatically delete most of these.
