6 spamc_selinux - Security Enhanced Linux Policy for the spamc processes
7
9 Security-Enhanced Linux secures the spamc processes via flexible manda‐
10 tory access control.
11 The spamc processes execute with the spamc_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15 For example:
17 ps -eZ | grep spamc_t
19
23 The spamc_t SELinux type can be entered via the spamc_exec_t file type.
24 The default entrypoint paths for the spamc_t domain are the following:
26 /usr/bin/razor.*, /usr/bin/pyzor, /usr/bin/spamc, /usr/bin/sa-learn,
28 /usr/bin/spamassassin
29
31 SELinux defines process types (domains) for each process running on the
32 system
33 You can see the context of a process using the -Z option to ps
35 Policy governs the access confined processes have to files. SELinux
37 spamc policy is very flexible allowing users to setup their spamc pro‐
38 cesses in as secure a method as possible.
39 The following process types are defined for spamc:
41 spamc_t
43 Note: semanage permissive -a spamc_t can be used to make the process
45 type spamc_t permissive. SELinux does not deny access to permissive
46 process types, but the AVC (SELinux denials) messages are still gener‐
47 ated.
48
51 SELinux policy is customizable based on least access required. spamc
52 policy is extremely flexible and has several booleans that allow you to
53 manipulate the policy and run spamc with the tightest access possible.
54 If you want to allow all domains to execute in fips_mode, you must turn
58 on the fips_mode boolean. Enabled by default.
59 setsebool -P fips_mode 1
61 If you want to allow http daemon to check spam, you must turn on the
65 httpd_can_check_spam boolean. Disabled by default.
66 setsebool -P httpd_can_check_spam 1
68 If you want to allow http daemon to send mail, you must turn on the
72 httpd_can_sendmail boolean. Disabled by default.
73 setsebool -P httpd_can_sendmail 1
75 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80 setsebool -P nis_enabled 1
82 If you want to allow user spamassassin clients to use the network, you
86 must turn on the spamassassin_can_network boolean. Disabled by default.
87 setsebool -P spamassassin_can_network 1
89
93 The SELinux process type spamc_t can manage files labeled with the fol‐
94 lowing file types. The paths listed are the default paths for these
95 file types. Note the processes UID still need to have DAC permissions.

158 SELinux requires files to have an extended attribute to define the file
159 type.
160 You can see the context of a file using the -Z option to ls
162 Policy governs the access confined processes have to these files.
164 SELinux spamc policy is very flexible allowing users to setup their
165 spamc processes in as secure a method as possible.
166 STANDARD FILE CONTEXT
168 SELinux defines the file context types for the spamc, if you wanted to
170 store files with these types in a different paths, you need to execute
171 the semanage command to specify alternate labeling and then use re‐
172 storecon to put the labels on disk.
173 semanage fcontext -a -t spamc_exec_t '/srv/spamc/content(/.*)?'
175 restorecon -R -v /srv/myspamc_content
176 Note: SELinux often uses regular expressions to specify labels that
178 match multiple files.
179 The following file types are defined for spamc:
181 spamc_exec_t
185 - Set files with the spamc_exec_t type, if you want to transition an
187 executable to the spamc_t domain.
188 Paths:
191 /usr/bin/razor.*, /usr/bin/pyzor, /usr/bin/spamc, /usr/bin/sa-
192 learn, /usr/bin/spamassassin
193 spamc_home_t
196 - Set files with the spamc_home_t type, if you want to store spamc
198 files in the users home directory.
199 Paths:
202 /root/.pyzor(/.*)?, /root/.razor(/.*)?, /root/.spamd(/.*)?,
203 /root/.spamassassin(/.*)?, /home/[^/]+/.pyzor(/.*)?,
204 /home/[^/]+/.razor(/.*)?, /home/[^/]+/.spamd(/.*)?,
205 /home/[^/]+/.spamassassin(/.*)?
206 spamc_tmp_t
209 - Set files with the spamc_tmp_t type, if you want to store spamc tem‐
211 porary files in the /tmp directories.
212 Note: File context can be temporarily modified with the chcon command.
216 If you want to permanently change the file context you need to use the
217 semanage fcontext command. This will modify the SELinux labeling data‐
218 base. You will need to use restorecon to apply the labels.
219
222 semanage fcontext can also be used to manipulate default file context
223 mappings.
224 semanage permissive can also be used to manipulate whether or not a
226 process type is permissive.
227 semanage module can also be used to enable/disable/install/remove pol‐
229 icy modules.
230 semanage boolean can also be used to manipulate the booleans
232 system-config-selinux is a GUI tool available to customize SELinux pol‐
235 icy settings.
