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
30

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 allow all domains to execute in fips_mode, you must turn
66       on the fips_mode boolean. Enabled by default.
67
68       setsebool -P fips_mode 1
69
70
71

PORT TYPES

73       SELinux defines port types to represent TCP and UDP ports.
74
75       You can see the types associated with a port  by  using  the  following
76       command:
77
78       semanage port -l
79
80
81       Policy  governs  the  access  confined  processes  have to these ports.
82       SELinux spamd policy is very flexible allowing  users  to  setup  their
83       spamd processes in as secure a method as possible.
84
85       The following port types are defined for spamd:
86
87
88       spamd_port_t
89
90
91
92       Default Defined Ports:
93                 tcp 783,10026,10027
94

MANAGED FILES

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

FILE CONTEXTS

253       SELinux requires files to have an extended attribute to define the file
254       type.
255
256       You can see the context of a file using the -Z option to ls
257
258       Policy governs the access  confined  processes  have  to  these  files.
259       SELinux  spamd  policy  is  very flexible allowing users to setup their
260       spamd processes in as secure a method as possible.
261
262       EQUIVALENCE DIRECTORIES
263
264
265       spamd policy stores data with multiple different file context types un‐
266       der  the  /var/lib/spamassassin  directory.  If you would like to store
267       the data in a different directory you can use the semanage  command  to
268       create  an equivalence mapping.  If you wanted to store this data under
269       the /srv directory you would execute the following command:
270
271       semanage fcontext -a -e /var/lib/spamassassin /srv/spamassassin
272       restorecon -R -v /srv/spamassassin
273
274       STANDARD FILE CONTEXT
275
276       SELinux defines the file context types for the spamd, if you wanted  to
277       store  files  with  these types in a diffent paths, you need to execute
278       the semanage command to specify alternate labeling  and  then  use  re‐
279       storecon to put the labels on disk.
280
281       semanage fcontext -a -t spamd_etc_t '/srv/myspamd_content(/.*)?'
282       restorecon -R -v /srv/myspamd_content
283
284       Note:  SELinux  often  uses  regular expressions to specify labels that
285       match multiple files.
286
287       The following file types are defined for spamd:
288
289
290
291       spamd_compiled_t
292
293       - Set files with the spamd_compiled_t type, if you want  to  treat  the
294       files as spamd compiled data.
295
296
297
298       spamd_etc_t
299

318
319
320       spamd_initrc_exec_t

323       tion an executable to the spamd_initrc_t domain.
324
325

329
330
331       spamd_log_t
332
333       - Set files with the spamd_log_t type, if you want to treat the data as
334       spamd log data, usually stored under the /var/log directory.
335
336
337       Paths:
338            /var/log/spamd.log.*,     /var/log/mimedefang.*,      /var/log/py‐
339            zord.log.*, /var/log/sa-update.log.*, /var/log/razor-agent.log.*
340
341
342       spamd_spool_t
343
344       - Set files with the spamd_spool_t type, if you want to store the spamd
345       files under the /var/spool directory.
346
347
348       Paths:
349            /var/spool/spamd(/.*)?,  /var/spool/spampd(/.*)?,  /var/spool/spa‐
350            massassin(/.*)?

356       porary files in the /tmp directories.
357
358
359
360       spamd_update_exec_t
361
362       - Set files with the spamd_update_exec_t type, if you want  to  transi‐
363       tion an executable to the spamd_update_t domain.
364
365
366       Paths:
367            /usr/share/spamassassin/sa-update.cron, /usr/bin/sa-update
368
369

390
391
392       Note:  File context can be temporarily modified with the chcon command.
393       If you want to permanently change the file context you need to use  the
394       semanage fcontext command.  This will modify the SELinux labeling data‐
395       base.  You will need to use restorecon to apply the labels.
396
397

COMMANDS

399       semanage fcontext can also be used to manipulate default  file  context
400       mappings.
401
402       semanage  permissive  can  also  be used to manipulate whether or not a
403       process type is permissive.
404
405       semanage module can also be used to enable/disable/install/remove  pol‐
406       icy modules.
407
408       semanage port can also be used to manipulate the port definitions
409
410       semanage boolean can also be used to manipulate the booleans
411
412
413       system-config-selinux is a GUI tool available to customize SELinux pol‐
414       icy settings.
