NAMEimapd - IMAP server process
SYNOPSISimapd [ -C config-file ] [ -U uses ] [ -T timeout ] [ -D ]
[ -s ] [ -N ] [ -p ssf ]
Imapd is an IMAP4rev1 server. It accepts commands on its standard
input and responds on its standard output. It MUST be invoked by mas‐
ter(8) with those descriptors attached to a remote client connection.
Imapd reads its configuration options out of the imapd.conf(5) file
unless specified otherwise by -C.
If the file msg/shutdown is created under the directory specified in
the configdirectory configuration option, then imapd will shut down the
connection, sending the first line contained in the file to the client
as the reason. New connections are denied.
If the file msg/motd is created under the directory specified in the
configdirectory configuration option, then imapd will send the first
line contained in the file to clients upon connect as an ALERT message
which IMAP-compliant clients are required to display. This option
serves to annoy users mostly. Unfortunately clients tend to connect
far more frequently than is apparent, causing each connection to gener‐
ate a seperate server ALERT for each connection. Many clients do not
display these properly, if they do anything with them at all.
If the directory log/user exists under the directory specified in the
configdirectory configuration option, then imapd will create protocol
telemetry logs for sessions authenticating as user. The telemetry logs
will be stored in the log/user directory with a filename of the imapd
Read configuration options from config-file.
The maximum number of times that the process should be used for
new connections before shutting down. The default is 250.
The number of seconds that the process will wait for a new con‐
nection before shutting down. Note that a value of 0 (zero)
will disable the timeout. The default is 60.
-D Run external debugger specified in debug_command.
-s Serve IMAP over SSL (imaps). All data to and from imapd is
encrypted using the Secure Sockets Layer.
-N Bypass password checking. (Not recommended unless you know what
-p ssf Tell imapd that an external layer exists. An SSF (security
strength factor) of 1 means an integrity protection layer
exists. Any higher SSF implies some form of privacy protection.
