DESCRIPTION

13       Imapd  is  an  IMAP4rev1  server.   It accepts commands on its standard
14       input and responds on its standard output.  It MUST be invoked by  mas‐
15       ter(8) with those descriptors attached to a remote client connection.
16
17       Imapd  reads  its  configuration  options out of the imapd.conf(5) file
18       unless specified otherwise by -C.
19
20       If the file msg/shutdown is created under the  directory  specified  in
21       the configdirectory configuration option, then imapd will shut down the
22       connection, sending the first line contained in the file to the  client
23       as the reason.  New connections are denied.
24
25       If  the  file  msg/motd is created under the directory specified in the
26       configdirectory configuration option, then imapd will  send  the  first
27       line  contained in the file to clients upon connect as an ALERT message
28       which IMAP-compliant clients are  required  to  display.   This  option
29       serves  to  annoy  users mostly.  Unfortunately clients tend to connect
30       far more frequently than is apparent, causing each connection to gener‐
31       ate  a  seperate server ALERT for each connection.  Many clients do not
32       display these properly, if they do anything with them at all.
33
34       If the directory log/user exists under the directory specified  in  the
35       configdirectory  configuration  option, then imapd will create protocol
36       telemetry logs for sessions authenticating as user.  The telemetry logs
37       will  be  stored in the log/user directory with a filename of the imapd
38       process-id.

OPTIONS

41       -C config-file
42              Read configuration options from config-file.
43
44       -U uses
45              The maximum number of times that the process should be used  for
46              new connections before shutting down.  The default is 250.
47
48       -T timeout
49              The  number of seconds that the process will wait for a new con‐
50              nection before shutting down.  Note that a  value  of  0  (zero)
51              will disable the timeout.  The default is 60.
52
53       -D     Run external debugger specified in debug_command.
54
55       -s     Serve  IMAP  over  SSL  (imaps).   All data to and from imapd is
56              encrypted using the Secure Sockets Layer.
57
58       -p ssf Tell imapd that an external  layer  exists.   An  SSF  (security
59              strength  factor)  of  1  means  an  integrity  protection layer
60              exists.  Any higher SSF implies some form of privacy protection.
