imapd - Internet Message Access Protocol (IMAP) server
process
/usr/sbin/imapd
The IMAP4rev1 server, imapd, accepts commands on its standard
input and responds on its standard output. It is
normally invoked by the inetd command and it reads its
configuration options out of the imapd.conf file.
If you want to take the IMAP server off line for a period
of time, you should notify the client systems. To do
this, create a msg/shutdown file, edit it, and state the
reason for the shut down. Set the owner of the msg directory
and the shutdown file to be the imap user. When a
client system tries to access the server, imapd sends the
first line contained in the shutdown file to the client
and closes the connection.
If you want to send a message to the IMAP clients without
disabling connections, create a msg/motd file, edit it,
and add your message. Set the owner of the msg directory
and the motd file to be the imap user. The server sends
the first line contained in the file to the clients upon
connection as an ALERT message, which IMAP-compliant
clients are required to display. Access to mailboxes is
unaffected.
For debugging purposes, create a log/user directory. When
this directory exists, the imapd daemon creates protocol
telemetry logs for sessions authenticating as user. The
telemetry logs are stored in the log/user directory with
the file name of the imapd process id.
The msg/shutdown and msg/motd files and the log/user
directory should be created under the directory specified
in the configdirectory configuration option of the
imapd.conf file. The default value is /var/imap, as in
/var/imap/msg/motd.
