Networking Glossary
- mail exploder Part of an electronic mail delivery system which allows a message to be delivered to a list of addressees. Mail exploders are used to implement mailing lists. Users send messages to a single address (e.g., hacks@somehost.edu) and the mail exploder takes care of delivery to the individual mailboxes in the list. [Source: RFC 1208]
- mail gateway A machine that connects two or more electronic mail systems (especially dissimilar mail systems on two different networks) and transfers messages between them. Sometimes the mapping and translation can be quite complex, and generally it 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. [Source: RFC 1208]
- MIB (Management Information Base) A collection of objects that can be accessed via a network management protocol. See SMI. [Source: RFC 1208]
- Martian Humorous term applied to packets that turn up unexpectedly on the wrong network because of bogus routing entries. Also used as a name for a packet which has an altogether bogus (non-registered or ill-formed) Internet address. [Source: RFC 1208]
- MTU (Maximum Transmission Unit) The largest possible unit of data that can be sent on a given physical medium. Example: The MTU of Ethernet is 1500 bytes. See fragmentation. [Source: RFC 1208]
