GNU Mailutils offers several server applications: pop3d,
imap4d, comsatd, to name a few. Being quite
different in their purpose, they are very similar in some aspects of
their architecture. First of all, they all support two operating
mode: a daemon mode, where a program disconnects from the controlling
terminal and works in background, and an inetd mode, where it
remains in foreground and communicates with the remote party via
standard input and output streams. Secondly, when operating as
daemons, they listen to a preconfigured set of IP addresses and
ports, reacting to requests that arrive.
To configure these aspects of functionality, GNU Mailutils provides Server Configuration Settings, which we will describe in this subsection.
