NAME

6       postfix_postqueue_selinux  -  Security  Enhanced  Linux  Policy for the
7       postfix_postqueue processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  postfix_postqueue_t  SELinux  type  can  be  entered via the post‐
25       fix_postqueue_exec_t file type.
26
27       The default entrypoint paths for the postfix_postqueue_t domain are the
28       following:
29
30       /usr/sbin/postqueue
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       postfix_postqueue policy is very flexible allowing users to setup their
40       postfix_postqueue processes in as secure a method as possible.
41
42       The following process types are defined for postfix_postqueue:
43
44       postfix_postqueue_t
45
46       Note: semanage permissive -a postfix_postqueue_t can be  used  to  make
47       the  process type postfix_postqueue_t permissive. SELinux does not deny
48       access to permissive process types, but the AVC (SELinux denials)  mes‐
49       sages are still generated.
50
51

BOOLEANS

53       SELinux  policy  is customizable based on least access required.  post‐
54       fix_postqueue policy is extremely flexible  and  has  several  booleans
55       that  allow you to manipulate the policy and run postfix_postqueue with
56       the tightest access possible.
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  system  to run with NIS, you must turn on the
68       nis_enabled boolean. Disabled by default.
69
70       setsebool -P nis_enabled 1

73

MANAGED FILES

75       The SELinux process type postfix_postqueue_t can manage  files  labeled
76       with  the following file types.  The paths listed are the default paths
77       for these file types.  Note the processes UID still need  to  have  DAC
78       permissions.
79
80       arpwatch_tmp_t
81
82
83       krb5_host_rcache_t
84
85            /var/tmp/krb5_0.rcache2
86            /var/cache/krb5rcache(/.*)?
87            /var/tmp/nfs_0
88            /var/tmp/DNS_25
89            /var/tmp/host_0
90            /var/tmp/imap_0
91            /var/tmp/HTTP_23
92            /var/tmp/HTTP_48
93            /var/tmp/ldap_55
94            /var/tmp/ldap_487
95            /var/tmp/ldapmap1_0
96
97       postfix_var_run_t
98
99            /var/spool/postfix/pid/.*

FILE CONTEXTS

103       SELinux requires files to have an extended attribute to define the file
104       type.
105
106       You can see the context of a file using the -Z option to ls
107
108       Policy governs the access  confined  processes  have  to  these  files.
109       SELinux  postfix_postqueue  policy  is  very flexible allowing users to
110       setup their postfix_postqueue processes in as secure a method as possi‐
111       ble.
112
113       The following file types are defined for postfix_postqueue:
114
115
116
117       postfix_postqueue_exec_t
118
119       -  Set  files  with  the  postfix_postqueue_exec_t type, if you want to
120       transition an executable to the postfix_postqueue_t domain.
121
122
123
124       Note: File context can be temporarily modified with the chcon  command.
125       If  you want to permanently change the file context you need to use the
126       semanage fcontext command.  This will modify the SELinux labeling data‐
127       base.  You will need to use restorecon to apply the labels.

COMMANDS

131       semanage  fcontext  can also be used to manipulate default file context
132       mappings.
133
134       semanage permissive can also be used to manipulate  whether  or  not  a
135       process type is permissive.
136
137       semanage  module can also be used to enable/disable/install/remove pol‐
138       icy modules.
139
140       semanage boolean can also be used to manipulate the booleans
141
142
143       system-config-selinux is a GUI tool available to customize SELinux pol‐
144       icy settings.
