NAME

6       qmail_smtpd_selinux   -   Security   Enhanced   Linux  Policy  for  the
7       qmail_smtpd processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the qmail_smtpd processes via  flexible
11       mandatory access control.
12
13       The  qmail_smtpd processes execute with the qmail_smtpd_t SELinux type.
14       You can check if you have these processes running by executing  the  ps
15       command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep qmail_smtpd_t

22

ENTRYPOINTS

24       The    qmail_smtpd_t    SELinux   type   can   be   entered   via   the
25       qmail_smtpd_exec_t file type.
26
27       The default entrypoint paths for the qmail_smtpd_t domain are the  fol‐
28       lowing:
29
30       /var/qmail/bin/qmail-smtpd
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       qmail_smtpd  policy  is  very  flexible  allowing  users to setup their
40       qmail_smtpd processes in as secure a method as possible.
41
42       The following process types are defined for qmail_smtpd:
43
44       qmail_smtpd_t
45
46       Note: semanage permissive -a qmail_smtpd_t can  be  used  to  make  the
47       process  type qmail_smtpd_t permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.

51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       qmail_smtpd policy is extremely flexible and has several booleans  that
55       allow  you to manipulate the policy and run qmail_smtpd with the tight‐
56       est access possible.
57
58
59
60       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
63       setsebool -P fips_mode 1
64
65
66
67       If  you  want  to allow confined applications to run with kerberos, you
68       must turn on the kerberos_enabled boolean. Enabled by default.
69
70       setsebool -P kerberos_enabled 1
71

73

FILE CONTEXTS

75       SELinux requires files to have an extended attribute to define the file
76       type.
77
78       You can see the context of a file using the -Z option to ls
79
80       Policy  governs  the  access  confined  processes  have to these files.
81       SELinux qmail_smtpd policy is very flexible  allowing  users  to  setup
82       their qmail_smtpd processes in as secure a method as possible.
83
84       STANDARD FILE CONTEXT
85
86       SELinux  defines  the  file  context  types for the qmail_smtpd, if you
87       wanted to store files with these types in a different paths,  you  need
88       to  execute the semanage command to specify alternate labeling and then
89       use restorecon to put the labels on disk.
90
91       semanage  fcontext  -a  -t  qmail_smtpd_exec_t   '/srv/qmail_smtpd/con‐
92       tent(/.*)?'
93       restorecon -R -v /srv/myqmail_smtpd_content
94
95       Note:  SELinux  often  uses  regular expressions to specify labels that
96       match multiple files.
97
98       The following file types are defined for qmail_smtpd:
99
100
101
102       qmail_smtpd_exec_t
103
104       - Set files with the qmail_smtpd_exec_t type, if you want to transition
105       an executable to the qmail_smtpd_t domain.
106
107
108
109       Note:  File context can be temporarily modified with the chcon command.
110       If you want to permanently change the file context you need to use  the
111       semanage fcontext command.  This will modify the SELinux labeling data‐
112       base.  You will need to use restorecon to apply the labels.
113
114

COMMANDS

116       semanage fcontext can also be used to manipulate default  file  context
117       mappings.
118
119       semanage  permissive  can  also  be used to manipulate whether or not a
120       process type is permissive.
121
122       semanage module can also be used to enable/disable/install/remove  pol‐
123       icy modules.
124
125       semanage boolean can also be used to manipulate the booleans
126
127
128       system-config-selinux is a GUI tool available to customize SELinux pol‐
129       icy settings.
