NAME
       dovecot_selinux	-  Security Enhanced Linux Policy for the dovecot pro‐
       cesses

DESCRIPTION
       Security-Enhanced Linux secures	the  dovecot  processes	 via  flexible
       mandatory access control.

       The  dovecot processes execute with the dovecot_t SELinux type. You can
       check if you have these processes running by executing the  ps  command
       with the -Z qualifier.

       For example:

       ps -eZ | grep dovecot_t

ENTRYPOINTS
       The  dovecot_t  SELinux type can be entered via the dovecot_exec_t file
       type.

       The default entrypoint paths for the dovecot_t domain are  the  follow‐
       ing:

       /usr/sbin/dovecot

PROCESS TYPES
       SELinux defines process types (domains) for each process running on the
       system

       You can see the context of a process using the -Z option to ps

       Policy governs the access confined processes have  to  files.   SELinux
       dovecot	policy	is very flexible allowing users to setup their dovecot
       processes in as secure a method as possible.

       The following process types are defined for dovecot:

       dovecot_deliver_t, dovecot_auth_t, dovecot_t

       Note: semanage permissive -a dovecot_t can be used to make the  process
       type  dovecot_t	permissive. SELinux does not deny access to permissive
       process types, but the AVC (SELinux denials) messages are still	gener‐
       ated.

BOOLEANS
       SELinux policy is customizable based on least access required.  dovecot
       policy is extremely flexible and has several booleans that allow you to
       manipulate  the	policy and run dovecot with the tightest access possi‐
       ble.

       If you want to allow users to resolve user passwd entries directly from
       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐

       If  you	want to allow all domains to have the kernel load modules, you
       must  turn  on  the  domain_kernel_load_modules	boolean.  Disabled  by
       default.

       setsebool -P domain_kernel_load_modules 1

       If you want to allow all domains to execute in fips_mode, you must turn
       on the fips_mode boolean. Enabled by default.

NSSWITCH DOMAIN
       If you want to allow users to resolve user passwd entries directly from
       ldap rather then using a sssd server for the dovecot_auth_t, dovecot_t,
       dovecot_deliver_t, you must  turn  on  the  authlogin_nsswitch_use_ldap
       boolean.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow confined applications to run with kerberos for the

FILE CONTEXTS
       SELinux requires files to have an extended attribute to define the file
       type.

       You can see the context of a file using the -Z option to ls

       Policy governs the access  confined  processes  have  to	 these	files.
       SELinux	dovecot	 policy is very flexible allowing users to setup their
       dovecot processes in as secure a method as possible.

       EQUIVALENCE DIRECTORIES

       dovecot policy stores data with multiple different file	context	 types
       under  the  /var/log/dovecot directory.	If you would like to store the
       data in a different directory you can use the semanage command to  cre‐
       ate an equivalence mapping.  If you wanted to store this data under the
       /srv dirctory you would execute the following command:

       semanage fcontext -a -e /var/log/dovecot /srv/dovecot
       restorecon -R -v /srv/dovecot

       STANDARD FILE CONTEXT

       SELinux defines the file context types for the dovecot, if  you	wanted
       to store files with these types in a diffent paths, you need to execute
       the semanage command  to	 sepecify  alternate  labeling	and  then  use
       restorecon to put the labels on disk.

       semanage	  fcontext   -a	  -t   dovecot_auth_exec_t  '/srv/dovecot/con‐
       tent(/.*)?'
       restorecon -R -v /srv/mydovecot_content

       Note: SELinux often uses regular expressions  to	 specify  labels  that
       match multiple files.

       The following file types are defined for dovecot:

       dovecot_auth_exec_t

       -  Set  files with the dovecot_auth_exec_t type, if you want to transi‐
       tion an executable to the dovecot_auth_t domain.

       Paths:
	    /usr/libexec/dovecot/auth, /usr/libexec/dovecot/dovecot-auth

       dovecot_auth_tmp_t

       - Set files with the dovecot_auth_tmp_t type,  if  you  want  to	 store
       dovecot auth temporary files in the /tmp directories.

       dovecot_cert_t

       -  Set  files  with  the	 dovecot_cert_t type, if you want to treat the
       files as dovecot certificate data.

       Paths:
	    /etc/pki/dovecot(/.*)?,	     /usr/share/ssl/certs/dovecot.pem,
	    /usr/share/ssl/private/dovecot.pem

       dovecot_deliver_exec_t

       -  Set files with the dovecot_deliver_exec_t type, if you want to tran‐
       sition an executable to the dovecot_deliver_t domain.

       Paths:
	    /usr/libexec/dovecot/deliver, /usr/libexec/dovecot/dovecot-lda

       dovecot_deliver_tmp_t

       - Set files with the dovecot_deliver_tmp_t type, if you want  to	 store
       dovecot deliver temporary files in the /tmp directories.

       dovecot_etc_t

       -  Set  files with the dovecot_etc_t type, if you want to store dovecot
       files in the /etc directories.

       Paths:
	    /etc/dovecot(/.*)?, /etc/dovecot.conf.*

       dovecot_exec_t

       - Set files with the dovecot_exec_t type, if you want to transition  an
       executable to the dovecot_t domain.

       dovecot_initrc_exec_t

       - Set files with the dovecot_initrc_exec_t type, if you want to transi‐
       tion an executable to the dovecot_initrc_t domain.

       dovecot_keytab_t

       - Set files with the dovecot_keytab_t type, if you want	to  treat  the
       files as kerberos keytab files.

       dovecot_passwd_t

       -  Set  files  with the dovecot_passwd_t type, if you want to treat the
       files as dovecot passwd data.

       dovecot_spool_t

       - Set files with the dovecot_spool_t type, if you  want	to  store  the
       dovecot files under the /var/spool directory.

       dovecot_tmp_t

       -  Set  files with the dovecot_tmp_t type, if you want to store dovecot
       temporary files in the /tmp directories.

       dovecot_var_lib_t

       - Set files with the dovecot_var_lib_t type, if you want to  store  the
       dovecot files under the /var/lib directory.

       Paths:
	    /var/lib/dovecot(/.*)?, /var/run/dovecot/login/ssl-parameters.dat

       dovecot_var_log_t

       -  Set  files with the dovecot_var_log_t type, if you want to treat the
       data as dovecot var log data, usually stored under the /var/log	direc‐
       tory.

       Paths:
	    /var/log/dovecot(/.*)?, /var/log/dovecot.log.*

       dovecot_var_run_t

       -  Set  files with the dovecot_var_run_t type, if you want to store the
       dovecot files under the /run or /var/run directory.

       Note: File context can be temporarily modified with the chcon  command.
       If  you want to permanently change the file context you need to use the
       semanage fcontext command.  This will modify the SELinux labeling data‐
       base.  You will need to use restorecon to apply the labels.

COMMANDS
       semanage	 fcontext  can also be used to manipulate default file context
       mappings.

       semanage permissive can also be used to manipulate  whether  or	not  a
       process type is permissive.

       semanage	 module can also be used to enable/disable/install/remove pol‐
       icy modules.

       semanage boolean can also be used to manipulate the booleans

       system-config-selinux is a GUI tool available to customize SELinux pol‐
       icy settings.
