imapd - Unix, Linux Command
NAME
imapd - IMAP server process
SYNOPSIS
imapd [
-C config-file ]
[
-U uses ]
[
-T timeout ]
[
-D ]
[
-s ]
[
-p ssf ]
DESCRIPTION
Imapd is an IMAP4rev1 server.
It accepts commands on its standard input and responds on its standard output.
It MUST be invoked by
master(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
generate 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 process-id.
OPTIONS
Tag | Description |
-C config-file | |
Read configuration options from config-file.
|
-U uses |
The maximum number of times that the process should be used for new
connections before shutting down. The default is 250.
|
-T timeout | |
The number of seconds that the process will wait for a new connection
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.
|
-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.
