This application relates to a method for sending and distributing e-mails and e-mail servers. According to the invention, whether the outline of an e-mail needs to be generated or not is judged according to the size of the e-mail and /or the number of addressees and /or the number of domains. If the outline of the e-mail does not need to be generated, the e-mail is directly sent to a server of a receiver. If the outline of the e-mail needs to be generated, the outline of the e-mail to be sent is generated and the following steps are executed: storing the e-mail in a server of a sender; sending the outline of the e-mail to a server of a receiver; and responding to an e-mail sending request which is received by the server of the sender and is sent by the receiver based on the outline, and sending the e-mail to the server of the receiver. Thus, the network bandwidth, and the storage space of the e-mail servers and user terminals are saved.
