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 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 For example:
18 ps -eZ | grep user_mail_t
20
24 The user_mail_t SELinux type can be entered via the sendmail_exec_t
25 file type.
26 The default entrypoint paths for the user_mail_t domain are the follow‐
28 ing:
29 /usr/sbin/sendmail(.sendmail)?, /usr/bin/esmtp, /usr/sbin/rmail,
31 /usr/sbin/ssmtp, /usr/lib/sendmail, /usr/bin/esmtp-wrapper,
32 /var/qmail/bin/sendmail, /usr/sbin/sendmail.postfix
33
35 SELinux defines process types (domains) for each process running on the
36 system
37 You can see the context of a process using the -Z option to ps
39 Policy governs the access confined processes have to files. SELinux
41 user_mail policy is very flexible allowing users to setup their
42 user_mail processes in as secure a method as possible.
43 The following process types are defined for user_mail:
45 user_mail_t
47 Note: semanage permissive -a user_mail_t can be used to make the
49 process type user_mail_t permissive. SELinux does not deny access to
50 permissive process types, but the AVC (SELinux denials) messages are
51 still generated.
52
55 SELinux policy is customizable based on least access required.
56 user_mail policy is extremely flexible and has several booleans that
57 allow you to manipulate the policy and run user_mail with the tightest
58 access possible.
59 If you want to allow users to resolve user passwd entries directly from
63 ldap rather then using a sssd server, you must turn on the authlo‐
64 gin_nsswitch_use_ldap boolean. Disabled by default.
65 setsebool -P authlogin_nsswitch_use_ldap 1
67 If you want to allow all domains to execute in fips_mode, you must turn
71 on the fips_mode boolean. Enabled by default.
72 setsebool -P fips_mode 1
74 If you want to allow confined applications to run with kerberos, you
78 must turn on the kerberos_enabled boolean. Enabled by default.
79 setsebool -P kerberos_enabled 1
81 If you want to allow system to run with NIS, you must turn on the
85 nis_enabled boolean. Disabled by default.
86 setsebool -P nis_enabled 1
88 If you want to allow confined applications to use nscd shared memory,
92 you must turn on the nscd_use_shm boolean. Disabled by default.
93 setsebool -P nscd_use_shm 1
95 If you want to support SAMBA home directories, you must turn on the
99 use_samba_home_dirs boolean. Disabled by default.
100 setsebool -P use_samba_home_dirs 1
102
106 The SELinux process type user_mail_t can manage files labeled with the
107 following file types. The paths listed are the default paths for these
108 file types. Note the processes UID still need to have DAC permissions.

194 semanage fcontext can also be used to manipulate default file context
195 mappings.
196 semanage permissive can also be used to manipulate whether or not a
198 process type is permissive.
199 semanage module can also be used to enable/disable/install/remove pol‐
201 icy modules.
202 semanage boolean can also be used to manipulate the booleans
204 system-config-selinux is a GUI tool available to customize SELinux pol‐
207 icy settings.
