IMAP4 daemon

imap4d has two operation modes:

Inetd
The server is started from `/etc/inetd.conf' file:
imap4  stream tcp nowait  root  /usr/local/sbin/imap4d imap4d
This is the default operation mode.
Standalone
The server runs as daemon, forking a child for each new connection. This mode is triggered by `-d' command line switch.

Command line options

`-d[NUMBER]'
`--daemon[=NUMBER]'
Run in standalone mode. An optional NUMBER specifies the maximum number of child processes the daemon is allowed to fork. When it is omitted, it defaults to 20 processes. Please note, that there should be no whitespace between the `-d' and its parameter.
`-h'
`--help'
Display short help message and exit.
`-i'
`--inetd'
Run in inetd mode.
`-p NUMBER'
`--port NUMBER'
Listen on given port NUMBER. This option is meaningful only in standalone mode. It defaults to port 143.
`-t NUMBER'
`--timeout NUMBER'
Set idle timeout to given NUMBER of seconds. Default is 1800 seconds (30 minutes). The daemon breaks the connection if it receives no commands from the client within that number of seconds.
`-v'
`--version'
Display program version and exit.
