6 dovecot_deliver_selinux - Security Enhanced Linux Policy for the dove‐
7 cot_deliver processes
8
10 Security-Enhanced Linux secures the dovecot_deliver processes via flex‐
11 ible mandatory access control.
12 The dovecot_deliver processes execute with the dovecot_deliver_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep dovecot_deliver_t
20
24 The dovecot_deliver_t SELinux type can be entered via the dovecot_de‐
25 liver_exec_t file type.
26 The default entrypoint paths for the dovecot_deliver_t domain are the
28 following:
29 /usr/libexec/dovecot/deliver, /usr/libexec/dovecot/dovecot-lda
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 dovecot_deliver policy is very flexible allowing users to setup their
40 dovecot_deliver processes in as secure a method as possible.
41 The following process types are defined for dovecot_deliver:
43 dovecot_deliver_t
45 Note: semanage permissive -a dovecot_deliver_t can be used to make the
47 process type dovecot_deliver_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. dove‐
54 cot_deliver policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run dovecot_deliver with the
56 tightest access possible.
57 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71
75 The SELinux process type dovecot_deliver_t can manage files labeled
76 with the following file types. The paths listed are the default paths
77 for these file types. Note the processes UID still need to have DAC
78 permissions.

137 SELinux requires files to have an extended attribute to define the file
138 type.
139 You can see the context of a file using the -Z option to ls
141 Policy governs the access confined processes have to these files.
143 SELinux dovecot_deliver policy is very flexible allowing users to setup
144 their dovecot_deliver processes in as secure a method as possible.
145 STANDARD FILE CONTEXT
147 SELinux defines the file context types for the dovecot_deliver, if you
149 wanted to store files with these types in a different paths, you need
150 to execute the semanage command to specify alternate labeling and then
151 use restorecon to put the labels on disk.
152 semanage fcontext -a -t dovecot_deliver_exec_t '/srv/dovecot_de‐
154 liver/content(/.*)?'
155 restorecon -R -v /srv/mydovecot_deliver_content
156 Note: SELinux often uses regular expressions to specify labels that
158 match multiple files.
159 The following file types are defined for dovecot_deliver:
161 dovecot_deliver_exec_t
165 - Set files with the dovecot_deliver_exec_t type, if you want to tran‐
167 sition an executable to the dovecot_deliver_t domain.
168 Paths:
171 /usr/libexec/dovecot/deliver, /usr/libexec/dovecot/dovecot-lda
172 dovecot_deliver_tmp_t
175 - Set files with the dovecot_deliver_tmp_t type, if you want to store
177 dovecot deliver temporary files in the /tmp directories.
178 Note: File context can be temporarily modified with the chcon command.
182 If you want to permanently change the file context you need to use the
183 semanage fcontext command. This will modify the SELinux labeling data‐
184 base. You will need to use restorecon to apply the labels.
185
188 semanage fcontext can also be used to manipulate default file context
189 mappings.
190 semanage permissive can also be used to manipulate whether or not a
192 process type is permissive.
193 semanage module can also be used to enable/disable/install/remove pol‐
195 icy modules.
196 semanage boolean can also be used to manipulate the booleans
198 system-config-selinux is a GUI tool available to customize SELinux pol‐
201 icy settings.
