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

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 sepecify 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

329
330
331 spamd_log_t
332

389 /var/spool/MD-Quarantine(/.*)?
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
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

413 system-config-selinux is a GUI tool available to customize SELinux pol‐
414 icy settings.
