NAME

6       postfix_cleanup_selinux  - Security Enhanced Linux Policy for the post‐
7       fix_cleanup processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the postfix_cleanup processes via flex‐
11       ible mandatory access control.
12
13       The   postfix_cleanup  processes  execute  with  the  postfix_cleanup_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_cleanup_t

22

ENTRYPOINTS

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

51

BOOLEANS

53       SELinux  policy  is customizable based on least access required.  post‐
54       fix_cleanup policy is extremely flexible and has several booleans  that
55       allow  you  to  manipulate  the policy and run postfix_cleanup with the
56       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

MANAGED FILES

75       The SELinux process type postfix_cleanup_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       anon_inodefs_t
81
82
83       postfix_spool_t
84
85            /var/spool/postfix.*
86            /var/spool/postfix/defer(/.*)?
87            /var/spool/postfix/flush(/.*)?
88            /var/spool/postfix/deferred(/.*)?
89            /var/spool/postfix/maildrop(/.*)?
90
91       postfix_var_run_t
92
93            /var/spool/postfix/pid/.*

FILE CONTEXTS

97       SELinux requires files to have an extended attribute to define the file
98       type.
99
100       You can see the context of a file using the -Z option to ls
101
102       Policy governs the access  confined  processes  have  to  these  files.
103       SELinux postfix_cleanup policy is very flexible allowing users to setup
104       their postfix_cleanup processes in as secure a method as possible.
105
106       STANDARD FILE CONTEXT
107
108       SELinux defines the file context types for the postfix_cleanup, if  you
109       wanted  to store files with these types in a diffent paths, you need to
110       execute the semanage command to sepecify alternate  labeling  and  then
111       use restorecon to put the labels on disk.
112
113       semanage    fcontext    -a   -t   postfix_cleanup_tmp_t   '/srv/mypost‐
114       fix_cleanup_content(/.*)?'
115       restorecon -R -v /srv/mypostfix_cleanup_content
116
117       Note: SELinux often uses regular expressions  to  specify  labels  that
118       match multiple files.
119
120       The following file types are defined for postfix_cleanup:
121
122
123
124       postfix_cleanup_exec_t
125
126       -  Set files with the postfix_cleanup_exec_t type, if you want to tran‐
127       sition an executable to the postfix_cleanup_t domain.
128
129
130
131       postfix_cleanup_tmp_t
132
133       - Set files with the postfix_cleanup_tmp_t type, if you want  to  store
134       postfix cleanup temporary files in the /tmp directories.
135
136
137
138       Note:  File context can be temporarily modified with the chcon command.
139       If you want to permanently change the file context you need to use  the
140       semanage fcontext command.  This will modify the SELinux labeling data‐
141       base.  You will need to use restorecon to apply the labels.
142
143

COMMANDS

145       semanage fcontext can also be used to manipulate default  file  context
146       mappings.
147
148       semanage  permissive  can  also  be used to manipulate whether or not a
149       process type is permissive.
150
151       semanage module can also be used to enable/disable/install/remove  pol‐
152       icy modules.
153
154       semanage boolean can also be used to manipulate the booleans
155
156
157       system-config-selinux is a GUI tool available to customize SELinux pol‐
158       icy settings.
