NAME

6       spamd_selinux - Security Enhanced Linux Policy for the spamd processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The spamd_t SELinux type can be entered via the spamd_exec_t file type.
24
25       The default entrypoint paths for the spamd_t domain are the following:
26
27       /usr/bin/spamd,  /usr/bin/pyzord,  /usr/sbin/spamd,   /usr/sbin/spampd,
28       /usr/bin/mimedefang,                   /usr/bin/mimedefang-multiplexor,
29       /usr/libexec/mimedefang-wrapper

PROCESS TYPES

32       SELinux defines process types (domains) for each process running on the
33       system
34
35       You can see the context of a process using the -Z option to ps
36
37       Policy  governs  the  access confined processes have to files.  SELinux
38       spamd policy is very flexible allowing users to setup their spamd  pro‐
39       cesses in as secure a method as possible.
40
41       The following process types are defined for spamd:
42
43       spamd_update_t, spamd_t
44
45       Note:  semanage  permissive  -a spamd_t can be used to make the process
46       type spamd_t permissive. SELinux does not  deny  access  to  permissive
47       process  types, but the AVC (SELinux denials) messages are still gener‐
48       ated.
49
50

BOOLEANS

52       SELinux policy is customizable based on least access  required.   spamd
53       policy is extremely flexible and has several booleans that allow you to
54       manipulate the policy and run spamd with the tightest access possible.
55
56
57
58       If you want to allow spamd to read/write  user  home  directories,  you
59       must turn on the spamd_enable_home_dirs boolean. Enabled by default.
60
61       setsebool -P spamd_enable_home_dirs 1
62
63
64
65       If  you  want  to  dontaudit all daemons scheduling requests (setsched,
66       sys_nice), you must turn on the  daemons_dontaudit_scheduling  boolean.
67       Enabled by default.
68
69       setsebool -P daemons_dontaudit_scheduling 1
70
71
72
73       If you want to allow all domains to execute in fips_mode, you must turn
74       on the fips_mode boolean. Enabled by default.
75
76       setsebool -P fips_mode 1
77
78
79
80       If you want to allow system to run with  NIS,  you  must  turn  on  the
81       nis_enabled boolean. Disabled by default.
82
83       setsebool -P nis_enabled 1
84
85
86

PORT TYPES

88       SELinux defines port types to represent TCP and UDP ports.
89
90       You  can  see  the  types associated with a port by using the following
91       command:
92
93       semanage port -l
94
95
96       Policy governs the access  confined  processes  have  to  these  ports.
97       SELinux  spamd  policy  is  very flexible allowing users to setup their
98       spamd processes in as secure a method as possible.
99
100       The following port types are defined for spamd:
101
102
103       spamd_port_t
104
105
106
107       Default Defined Ports:
108                 tcp 783,10026,10027
109

MANAGED FILES

111       The SELinux process type spamd_t can manage files labeled with the fol‐
112       lowing  file  types.   The paths listed are the default paths for these
113       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

268       SELinux requires files to have an extended attribute to define the file
269       type.
270
271       You can see the context of a file using the -Z option to ls
272
273       Policy  governs  the  access  confined  processes  have to these files.
274       SELinux spamd policy is very flexible allowing  users  to  setup  their
275       spamd processes in as secure a method as possible.
276
277       EQUIVALENCE DIRECTORIES
278
279
280       spamd policy stores data with multiple different file context types un‐
281       der the /var/lib/spamassassin directory.  If you would  like  to  store
282       the  data  in a different directory you can use the semanage command to
283       create an equivalence mapping.  If you wanted to store this data  under
284       the /srv directory you would execute the following command:
285
286       semanage fcontext -a -e /var/lib/spamassassin /srv/spamassassin
287       restorecon -R -v /srv/spamassassin
288
289       STANDARD FILE CONTEXT
290
291       SELinux  defines the file context types for the spamd, if you wanted to
292       store files with these types in a different paths, you need to  execute
293       the  semanage  command  to  specify alternate labeling and then use re‐
294       storecon to put the labels on disk.
295
296       semanage fcontext -a -t spamd_update_exec_t '/srv/spamd/content(/.*)?'
297       restorecon -R -v /srv/myspamd_content
298
299       Note: SELinux often uses regular expressions  to  specify  labels  that
300       match multiple files.
301
302       The following file types are defined for spamd:
303
304
305
306       spamd_compiled_t

423
424
425       Note:  File context can be temporarily modified with the chcon command.
426       If you want to permanently change the file context you need to use  the
427       semanage fcontext command.  This will modify the SELinux labeling data‐
428       base.  You will need to use restorecon to apply the labels.
429
430

COMMANDS

432       semanage fcontext can also be used to manipulate default  file  context
433       mappings.
434
435       semanage  permissive  can  also  be used to manipulate whether or not a
436       process type is permissive.
437
438       semanage module can also be used to enable/disable/install/remove  pol‐
439       icy modules.
440
441       semanage port can also be used to manipulate the port definitions
442
443       semanage boolean can also be used to manipulate the booleans
444
445
446       system-config-selinux is a GUI tool available to customize SELinux pol‐
447       icy settings.
