6 spamass_milter_selinux - Security Enhanced Linux Policy for the spa‐
7 mass_milter processes
8
10 Security-Enhanced Linux secures the spamass_milter processes via flexi‐
11 ble mandatory access control.
12 The spamass_milter processes execute with the spamass_milter_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep spamass_milter_t
20
24 The spamass_milter_t SELinux type can be entered via the spamass_mil‐
25 ter_exec_t file type.
26 The default entrypoint paths for the spamass_milter_t domain are the
28 following:
29 /usr/sbin/spamass-milter
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 spamass_milter policy is very flexible allowing users to setup their
40 spamass_milter processes in as secure a method as possible.
41 The following process types are defined for spamass_milter:
43 spamass_milter_t
45 Note: semanage permissive -a spamass_milter_t can be used to make the
47 process type spamass_milter_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. spa‐
54 mass_milter policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run spamass_milter with the
56 tightest access possible.

133 The SELinux process type spamass_milter_t can manage files labeled with
134 the following file types. The paths listed are the default paths for
135 these file types. Note the processes UID still need to have DAC per‐
136 missions.

202 SELinux requires files to have an extended attribute to define the file
203 type.
204 You can see the context of a file using the -Z option to ls
206 Policy governs the access confined processes have to these files.
208 SELinux spamass_milter policy is very flexible allowing users to setup
209 their spamass_milter processes in as secure a method as possible.
210 EQUIVALENCE DIRECTORIES
212 spamass_milter policy stores data with multiple different file context
215 types under the /var/run/spamass-milter directory. If you would like
216 to store the data in a different directory you can use the semanage
217 command to create an equivalence mapping. If you wanted to store this
218 data under the /srv dirctory you would execute the following command:
219 semanage fcontext -a -e /var/run/spamass-milter /srv/spamass-milter
221 restorecon -R -v /srv/spamass-milter
222 STANDARD FILE CONTEXT
224 SELinux defines the file context types for the spamass_milter, if you
226 wanted to store files with these types in a diffent paths, you need to
227 execute the semanage command to sepecify alternate labeling and then
228 use restorecon to put the labels on disk.
229 semanage fcontext -a -t spamass_milter_state_t '/srv/myspamass_mil‐
231 ter_content(/.*)?'
232 restorecon -R -v /srv/myspamass_milter_content
233 Note: SELinux often uses regular expressions to specify labels that
235 match multiple files.
236 The following file types are defined for spamass_milter:
238 spamass_milter_data_t
242 - Set files with the spamass_milter_data_t type, if you want to treat
244 the files as spamass milter content.
245 Paths:
248 /var/run/spamass-milter(/.*)?, /var/run/spamass-milter.pid
249 spamass_milter_exec_t
252 - Set files with the spamass_milter_exec_t type, if you want to transi‐
254 tion an executable to the spamass_milter_t domain.
255 spamass_milter_state_t
259 - Set files with the spamass_milter_state_t type, if you want to treat
261 the files as spamass milter state data.
262 Note: File context can be temporarily modified with the chcon command.
266 If you want to permanently change the file context you need to use the
267 semanage fcontext command. This will modify the SELinux labeling data‐
268 base. You will need to use restorecon to apply the labels.
269
272 semanage fcontext can also be used to manipulate default file context
273 mappings.
274 semanage permissive can also be used to manipulate whether or not a
276 process type is permissive.
277 semanage module can also be used to enable/disable/install/remove pol‐
279 icy modules.
280 semanage boolean can also be used to manipulate the booleans
282 system-config-selinux is a GUI tool available to customize SELinux pol‐
285 icy settings.
