6 mailman_mail_selinux - Security Enhanced Linux Policy for the mail‐
7 man_mail processes
8
10 Security-Enhanced Linux secures the mailman_mail processes via flexible
11 mandatory access control.
12 The mailman_mail processes execute with the mailman_mail_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 mailman_mail_t
20
24 The mailman_mail_t SELinux type can be entered via the mail‐
25 man_mail_exec_t file type.
26 The default entrypoint paths for the mailman_mail_t domain are the fol‐
28 lowing:
29 /usr/lib(64)?/mailman/mail/mailman, /usr/lib(64)?/mailman/bin/mail‐
31 manctl, /usr/lib(64)?/mailman/scripts/mailman
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 mailman_mail policy is very flexible allowing users to setup their
41 mailman_mail processes in as secure a method as possible.
42 The following process types are defined for mailman_mail:
44 mailman_mail_t
46 Note: semanage permissive -a mailman_mail_t can be used to make the
48 process type mailman_mail_t permissive. SELinux does not deny access to
49 permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
54 SELinux policy is customizable based on least access required. mail‐
55 man_mail policy is extremely flexible and has several booleans that
56 allow you to manipulate the policy and run mailman_mail with the tight‐
57 est access possible.

155 The SELinux process type mailman_mail_t can manage files labeled with
156 the following file types. The paths listed are the default paths for
157 these file types. Note the processes UID still need to have DAC per‐
158 missions.

244 SELinux requires files to have an extended attribute to define the file
245 type.
246 You can see the context of a file using the -Z option to ls
248 Policy governs the access confined processes have to these files.
250 SELinux mailman_mail policy is very flexible allowing users to setup
251 their mailman_mail processes in as secure a method as possible.
252 STANDARD FILE CONTEXT
254 SELinux defines the file context types for the mailman_mail, if you
256 wanted to store files with these types in a diffent paths, you need to
257 execute the semanage command to sepecify alternate labeling and then
258 use restorecon to put the labels on disk.
259 semanage fcontext -a -t mailman_mail_tmp_t '/srv/mymailman_mail_con‐
261 tent(/.*)?'
262 restorecon -R -v /srv/mymailman_mail_content
263 Note: SELinux often uses regular expressions to specify labels that
265 match multiple files.
266 The following file types are defined for mailman_mail:
268 mailman_mail_exec_t
272 - Set files with the mailman_mail_exec_t type, if you want to transi‐
274 tion an executable to the mailman_mail_t domain.
275 Paths:
278 /usr/lib(64)?/mailman/mail/mailman, /usr/lib(64)?/mail‐
279 man/bin/mailmanctl, /usr/lib(64)?/mailman/scripts/mailman
280 mailman_mail_tmp_t
283 - Set files with the mailman_mail_tmp_t type, if you want to store
285 mailman mail temporary files in the /tmp directories.
286 Note: File context can be temporarily modified with the chcon command.
290 If you want to permanently change the file context you need to use the
291 semanage fcontext command. This will modify the SELinux labeling data‐
292 base. You will need to use restorecon to apply the labels.
293
296 semanage fcontext can also be used to manipulate default file context
297 mappings.
298 semanage permissive can also be used to manipulate whether or not a
300 process type is permissive.
301 semanage module can also be used to enable/disable/install/remove pol‐
303 icy modules.
304 semanage boolean can also be used to manipulate the booleans
306 system-config-selinux is a GUI tool available to customize SELinux pol‐
309 icy settings.
