NAME

6       system_mail_selinux  -  Security  Enhanced  Linux  Policy  for the sys‐
7       tem_mail processes
8

DESCRIPTION

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

PROCESS TYPES

24       SELinux defines process types (domains) for each process running on the
25       system
26
27       You can see the context of a process using the -Z option to ps
28
29       Policy governs the access confined processes have  to  files.   SELinux
30       system_mail  policy is very flexible allowing users to setup their sys‐
31       tem_mail processes in as secure a method as possible.
32
33       The following process types are defined for system_mail:
34
35       system_mail_t
36
37       Note: semanage permissive -a system_mail_t can  be  used  to  make  the
38       process  type system_mail_t permissive. SELinux does not deny access to
39       permissive process types, but the AVC (SELinux  denials)  messages  are
40       still generated.

42

BOOLEANS

44       SELinux  policy  is  customizable based on least access required.  sys‐
45       tem_mail policy is extremely flexible and has several booleans that al‐
46       low  you to manipulate the policy and run system_mail with the tightest
47       access possible.
48
49
50
51       If you want to allow all domains to execute in fips_mode, you must turn
52       on the fips_mode boolean. Enabled by default.
53
54       setsebool -P fips_mode 1
55
56
57
58       If  you  want to determine whether Gitosis can send mail, you must turn
59       on the gitosis_can_sendmail boolean. Disabled by default.
60
61       setsebool -P gitosis_can_sendmail 1
62
63
64
65       If you want to allow http daemon to send mail, you  must  turn  on  the
66       httpd_can_sendmail boolean. Disabled by default.
67
68       setsebool -P httpd_can_sendmail 1
69
70
71
72       If  you  want  to  allow  system  to run with NIS, you must turn on the
73       nis_enabled boolean. Disabled by default.
74
75       setsebool -P nis_enabled 1
76
77
78
79       If you want to allow Redis to run redis-sentinal notification  scripts,
80       you must turn on the redis_enable_notify boolean. Disabled by default.
81
82       setsebool -P redis_enable_notify 1
83
84
85
86       If  you want to support ecryptfs home directories, you must turn on the
87       use_ecryptfs_home_dirs boolean. Disabled by default.
88
89       setsebool -P use_ecryptfs_home_dirs 1

MANAGED FILES

94       The SELinux process type system_mail_t can manage  files  labeled  with
95       the  following  file types.  The paths listed are the default paths for
96       these file types.  Note the processes UID still need to have  DAC  per‐
97       missions.

207       semanage  fcontext  can also be used to manipulate default file context
208       mappings.
209
210       semanage permissive can also be used to manipulate  whether  or  not  a
211       process type is permissive.
212
213       semanage  module can also be used to enable/disable/install/remove pol‐
214       icy modules.
215
216       semanage boolean can also be used to manipulate the booleans
217
218
219       system-config-selinux is a GUI tool available to customize SELinux pol‐
