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.
57
58
59
60       If you want to allow all domains to execute in fips_mode, you must turn
61       on the fips_mode boolean. Enabled by default.
62
63       setsebool -P fips_mode 1
64
65
66
67       If  you  want  to allow confined applications to run with kerberos, you
68       must turn on the kerberos_enabled boolean. Disabled by default.
69
70       setsebool -P kerberos_enabled 1
71
72
73

MANAGED FILES

75       The SELinux process type dovecot_t can manage files  labeled  with  the
76       following file types.  The paths listed are the default paths for these
77       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

178       SELinux requires files to have an extended attribute to define the file
179       type.
180
181       You can see the context of a file using the -Z option to ls
182
183       Policy  governs  the  access  confined  processes  have to these files.
184       SELinux dovecot policy is very flexible allowing users to  setup  their
185       dovecot processes in as secure a method as possible.
186
187       EQUIVALENCE DIRECTORIES
188
189
190       dovecot  policy  stores data with multiple different file context types
191       under the /var/log/dovecot directory.  If you would like to  store  the
192       data  in a different directory you can use the semanage command to cre‐
193       ate an equivalence mapping.  If you wanted to store this data under the
194       /srv directory you would execute the following command:
195
196       semanage fcontext -a -e /var/log/dovecot /srv/dovecot
197       restorecon -R -v /srv/dovecot
198
199       STANDARD FILE CONTEXT
200
201       SELinux  defines  the file context types for the dovecot, if you wanted
202       to store files with these types in a diffent paths, you need to execute
203       the  semanage  command  to  sepecify  alternate  labeling  and then use
204       restorecon to put the labels on disk.
205
206       semanage  fcontext   -a   -t   dovecot_var_run_t   '/srv/mydovecot_con‐
207       tent(/.*)?'
208       restorecon -R -v /srv/mydovecot_content
209
210       Note:  SELinux  often  uses  regular expressions to specify labels that
211       match multiple files.
212
213       The following file types are defined for dovecot:
214

342       Note:  File context can be temporarily modified with the chcon command.
343       If you want to permanently change the file context you need to use  the
344       semanage fcontext command.  This will modify the SELinux labeling data‐
345       base.  You will need to use restorecon to apply the labels.
346
347

COMMANDS

349       semanage fcontext can also be used to manipulate default  file  context
350       mappings.
351
352       semanage  permissive  can  also  be used to manipulate whether or not a
353       process type is permissive.
354
355       semanage module can also be used to enable/disable/install/remove  pol‐
356       icy modules.
357
358       semanage boolean can also be used to manipulate the booleans
359
360
361       system-config-selinux is a GUI tool available to customize SELinux pol‐
362       icy settings.
