邮件网关,(介於两个信件系统间,使其能够互相传递邮件的机器)
mail gatewayA machine that connects two or more {electronic mail} systems (including dissimilar mail systems) and transfers messages between them. Sometimes the mapping and translation can be quite complex, and it generally requires a {store and forward} scheme whereby the message is received from one system completely before it is transmitted to the next system, after suitable translations.
