6 user_mail_selinux - Security Enhanced Linux Policy for the user_mail
7 processes
8
10 Security-Enhanced Linux secures the user_mail processes via flexible
11 mandatory access control.
12
13 The user_mail processes execute with the user_mail_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep user_mail_t
20
21
22
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 user_mail policy is very flexible allowing users to setup their
31 user_mail processes in as secure a method as possible.
32
33 The following process types are defined for user_mail:
34
35 user_mail_t
36
37 Note: semanage permissive -a user_mail_t can be used to make the
38 process type user_mail_t permissive. SELinux does not deny access to
39 permissive process types, but the AVC (SELinux denials) messages are
40 still generated.
41
42
44 SELinux policy is customizable based on least access required.
45 user_mail policy is extremely flexible and has several booleans that
46 allow you to manipulate the policy and run user_mail with the tightest
47 access possible.

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 allow system to run with NIS, you must turn on the
59 nis_enabled boolean. Disabled by default.
60
61 setsebool -P nis_enabled 1
62
63
64
65 If you want to support SAMBA home directories, you must turn on the
66 use_samba_home_dirs boolean. Disabled by default.
67
68 setsebool -P use_samba_home_dirs 1

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

156 semanage fcontext can also be used to manipulate default file context
157 mappings.

159 semanage permissive can also be used to manipulate whether or not a
160 process type is permissive.

163 icy modules.
