2 Glossary of Frequently Used Terms

Authentication

A process whereby Anubis determines authenticity of the connecting party, its user name and configuration settings.

Protocol

A standard for information exchange. Protocol defines specific wording and control flow for communications between two or more programs, devices or systems.

SMTP

Simple Mail Transport Protocol is a common mechanism for exchanging mail across a network. This was described initially in RFC 821, and subsequently extended by more documents, the most recent one being RFC 5321.

Daemon

A process that runs in the background, doing automated processing.

Server

A server provides information or other services for its clients. Most network protocols are client–server based. This term often refers to hardware, but it can also refer (and we’re using it that way) to a particular program or process, on that machine, which provides the service.

Proxy

A program, which goes between MUA and MTA. It can be used as a gateway to the outside world, while using a firewall. In this case a host under the firewall sends data to the proxy server, which in turn forwards it to a server outside, receives its replies, and passes them back to the internal host.

Guile

GNU’s Ubiquitous Intelligent Language for Extensions. It provides a Scheme interpreter conforming to the R5RS language specification. GNU Anubis uses Guile as its extension language. For more information about Guile, Overview in The Guile Reference Manual.

GPG

GNU Privacy Guard, a tool compatible with PGP (Pretty Good Privacy).
