imapd(8)imapd(8)NAMEimapd - Internet Message Access Protocol (IMAP) server process
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
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 direc‐
tory exists, the imapd daemon creates protocol telemetry logs for ses‐
sions 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 config‐
uration option of the imapd.conf file. The default value is /var/imap,
as in /var/imap/msg/motd.
