NAME

6       mailman_mail_selinux  -  Security  Enhanced  Linux Policy for the mail‐
7       man_mail processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the mailman_mail processes via flexible
11       mandatory access control.
12
13       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
17       For example:
18
19       ps -eZ | grep mailman_mail_t
20
21
22

ENTRYPOINTS

24       The   mailman_mail_t   SELinux  type  can  be  entered  via  the  mail‐
25       man_mail_exec_t file type.
26
27       The default entrypoint paths for the mailman_mail_t domain are the fol‐
28       lowing:
29
30       /usr/mailman.*/mail/wrapper,           /usr/lib/mailman.*/mail/mailman,
31       /usr/lib/mailman.*/mail/wrapper,     /usr/lib/mailman.*/bin/mailmanctl,
32       /usr/lib/mailman.*/scripts/mailman,      /usr/lib/mailman.*/bin/mm-han‐
33       dler.*, /usr/share/doc/mailman.*/mm-handler.*, /usr/lib/mailman/bin/mm-
34       handler.*, /usr/lib/mailman/bin/mailmanctl
35

PROCESS TYPES

37       SELinux defines process types (domains) for each process running on the
38       system
39
40       You can see the context of a process using the -Z option to ps
41
42       Policy governs the access confined processes have  to  files.   SELinux
43       mailman_mail  policy  is  very  flexible  allowing users to setup their
44       mailman_mail processes in as secure a method as possible.
45
46       The following process types are defined for mailman_mail:
47
48       mailman_mail_t
49
50       Note: semanage permissive -a mailman_mail_t can be  used  to  make  the
51       process type mailman_mail_t permissive. SELinux does not deny access to
52       permissive process types, but the AVC (SELinux  denials)  messages  are
53       still generated.
54
55

BOOLEANS

57       SELinux  policy  is customizable based on least access required.  mail‐
58       man_mail policy is extremely flexible and  has  several  booleans  that
59       allow you to manipulate the policy and run mailman_mail with the tight‐
60       est access possible.

183       the following file types.  The paths listed are the default  paths  for
184       these  file  types.  Note the processes UID still need to have DAC per‐

FILE CONTEXTS

257       SELinux requires files to have an extended attribute to define the file
258       type.
259
260       You can see the context of a file using the -Z option to ls
261
262       Policy  governs  the  access  confined  processes  have to these files.
263       SELinux mailman_mail policy is very flexible allowing  users  to  setup
264       their mailman_mail processes in as secure a method as possible.
265
266       STANDARD FILE CONTEXT
267
268       SELinux  defines  the  file  context types for the mailman_mail, if you
269       wanted to store files with these types in a diffent paths, you need  to
270       execute  the  semanage  command to sepecify alternate labeling and then
271       use restorecon to put the labels on disk.
272
273       semanage fcontext -a  -t  mailman_mail_tmp_t  '/srv/mymailman_mail_con‐
274       tent(/.*)?'
275       restorecon -R -v /srv/mymailman_mail_content
276
277       Note:  SELinux  often  uses  regular expressions to specify labels that
278       match multiple files.
279
280       The following file types are defined for mailman_mail:
281
282
283
284       mailman_mail_exec_t
285
286       - Set files with the mailman_mail_exec_t type, if you want  to  transi‐
287       tion an executable to the mailman_mail_t domain.
288
289
290       Paths:
291            /usr/mailman.*/mail/wrapper,      /usr/lib/mailman.*/mail/mailman,
292            /usr/lib/mailman.*/mail/wrapper,      /usr/lib/mailman.*/bin/mail‐
293            manctl,     /usr/lib/mailman.*/scripts/mailman,     /usr/lib/mail‐
294            man.*/bin/mm-handler.*,     /usr/share/doc/mailman.*/mm-handler.*,
295            /usr/lib/mailman/bin/mm-handler.*, /usr/lib/mailman/bin/mailmanctl
296
297
298       mailman_mail_tmp_t
299
300       -  Set  files  with  the  mailman_mail_tmp_t type, if you want to store
301       mailman mail temporary files in the /tmp directories.
302
303
304
305       Note: File context can be temporarily modified with the chcon  command.
306       If  you want to permanently change the file context you need to use the
307       semanage fcontext command.  This will modify the SELinux labeling data‐
308       base.  You will need to use restorecon to apply the labels.
309
310

COMMANDS

312       semanage  fcontext  can also be used to manipulate default file context
313       mappings.
314
315       semanage permissive can also be used to manipulate  whether  or  not  a
316       process type is permissive.
317
318       semanage  module can also be used to enable/disable/install/remove pol‐
319       icy modules.
320
321       semanage boolean can also be used to manipulate the booleans
322
323
324       system-config-selinux is a GUI tool available to customize SELinux pol‐
325       icy settings.
