NAME

6       dovecot_selinux  -  Security Enhanced Linux Policy for the dovecot pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  dovecot  processes  via  flexible
11       mandatory access control.
12
13       The  dovecot processes execute with the dovecot_t SELinux type. You can
14       check if you have these processes running by executing the  ps  command
15       with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep dovecot_t
20
21
22

ENTRYPOINTS

24       The  dovecot_t  SELinux type can be entered via the dovecot_exec_t file
25       type.
26
27       The default entrypoint paths for the dovecot_t domain are  the  follow‐
28       ing:
29
30       /usr/sbin/dovecot
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       dovecot  policy  is very flexible allowing users to setup their dovecot
40       processes in as secure a method as possible.
41
42       The following process types are defined for dovecot:
43
44       dovecot_t, dovecot_auth_t, dovecot_deliver_t
45
46       Note: semanage permissive -a dovecot_t can be used to make the  process
47       type  dovecot_t  permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux policy is customizable based on least access required.  dovecot
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run dovecot with the tightest access possi‐
56       ble.

FILE CONTEXTS

317       SELinux requires files to have an extended attribute to define the file
318       type.
319
320       You can see the context of a file using the -Z option to ls
321
322       Policy  governs  the  access  confined  processes  have to these files.
323       SELinux dovecot policy is very flexible allowing users to  setup  their
324       dovecot processes in as secure a method as possible.
325
326       EQUIVALENCE DIRECTORIES
327
328
329       dovecot  policy  stores data with multiple different file context types
330       under the /var/log/dovecot directory.  If you would like to  store  the
331       data  in a different directory you can use the semanage command to cre‐
332       ate an equivalence mapping.  If you wanted to store this data under the
333       /srv dirctory you would execute the following command:
334
335       semanage fcontext -a -e /var/log/dovecot /srv/dovecot
336       restorecon -R -v /srv/dovecot
337
338       STANDARD FILE CONTEXT
339
340       SELinux  defines  the file context types for the dovecot, if you wanted
341       to store files with these types in a diffent paths, you need to execute
342       the  semanage  command  to  sepecify  alternate  labeling  and then use
343       restorecon to put the labels on disk.
344
345       semanage  fcontext   -a   -t   dovecot_var_run_t   '/srv/mydovecot_con‐
346       tent(/.*)?'
347       restorecon -R -v /srv/mydovecot_content
348
349       Note:  SELinux  often  uses  regular expressions to specify labels that
350       match multiple files.
351
352       The following file types are defined for dovecot:
353
354
355
356       dovecot_auth_exec_t
357

481       Note:  File context can be temporarily modified with the chcon command.
482       If you want to permanently change the file context you need to use  the
483       semanage fcontext command.  This will modify the SELinux labeling data‐
484       base.  You will need to use restorecon to apply the labels.
485
486

COMMANDS

488       semanage fcontext can also be used to manipulate default  file  context
489       mappings.
490
491       semanage  permissive  can  also  be used to manipulate whether or not a
492       process type is permissive.
493
494       semanage module can also be used to enable/disable/install/remove  pol‐
495       icy modules.
496
497       semanage boolean can also be used to manipulate the booleans
498
499
500       system-config-selinux is a GUI tool available to customize SELinux pol‐
501       icy settings.
