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.

136 SELinux requires files to have an extended attribute to define the file
137 type.
138 You can see the context of a file using the -Z option to ls
140 Policy governs the access confined processes have to these files.
142 SELinux dovecot_deliver policy is very flexible allowing users to setup
143 their dovecot_deliver processes in as secure a method as possible.
144 STANDARD FILE CONTEXT
146 SELinux defines the file context types for the dovecot_deliver, if you
148 wanted to store files with these types in a diffent paths, you need to
149 execute the semanage command to specify alternate labeling and then use
150 restorecon to put the labels on disk.
151 semanage fcontext -a -t dovecot_deliver_tmp_t '/srv/mydovecot_de‐
153 liver_content(/.*)?'
154 restorecon -R -v /srv/mydovecot_deliver_content
155 Note: SELinux often uses regular expressions to specify labels that
157 match multiple files.
158 The following file types are defined for dovecot_deliver:
160 dovecot_deliver_exec_t
164 - Set files with the dovecot_deliver_exec_t type, if you want to tran‐
166 sition an executable to the dovecot_deliver_t domain.
167 Paths:
170 /usr/libexec/dovecot/deliver, /usr/libexec/dovecot/dovecot-lda
171 dovecot_deliver_tmp_t
174 - Set files with the dovecot_deliver_tmp_t type, if you want to store
176 dovecot deliver temporary files in the /tmp directories.
177 Note: File context can be temporarily modified with the chcon command.
181 If you want to permanently change the file context you need to use the
182 semanage fcontext command. This will modify the SELinux labeling data‐
183 base. You will need to use restorecon to apply the labels.
184
187 semanage fcontext can also be used to manipulate default file context
188 mappings.
189 semanage permissive can also be used to manipulate whether or not a
191 process type is permissive.
192 semanage module can also be used to enable/disable/install/remove pol‐
194 icy modules.
195 semanage boolean can also be used to manipulate the booleans
197 system-config-selinux is a GUI tool available to customize SELinux pol‐
200 icy settings.
