We also need a policy for opendmarc: # service opendmarc status opendmarc is stopped # service opendmarc start Starting OpenDMARC Milter: [ OK ] # service opendmarc status opendmarc (pid 16994) is running... # ps -efZ | grep dmarc unconfined_u:system_r:initrc_t:s0 498 16994 1 0 05:46 ? 00:00:00 /usr/sbin/opendmarc -c /etc/opendmarc.conf -P /var/run/opendmarc/opendmarc.pid unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 root 17007 12434 0 05:46 pts/0 00:00:00 grep dmarc # Testing an SELinux policy is preferably done on EL6 since that's what my mailserver runs on. So it would be most appreciated if you could make a policy available for EL6 first or in addition to one for Fedora. Thanks! Could you try to execute # chcon -t dkim_milter_exec_t /usr/sbin/opendmarc # chcon -R -t dkim_milter_data_t /var/run/opendmarc /var/spool/opendmarc and re-test it. Thank you. Hi Miroslav. Here are the results: Old: $ ls -Z /usr/sbin/opendmarc -rwxr-xr-x. root root system_u:object_r:bin_t:s0 /usr/sbin/opendmarc $ ls -Z /var/spool/opendmarc/ -rw-rw----. opendmarc mail unconfined_u:object_r:var_spool_t:s0 opendmarc.dat Change: $ sudo chcon -t dkim_milter_exec_t /usr/sbin/opendmarc $ chcon -R -t dkim_milter_data_t /var/run/opendmarc /var/spool/opendmarc New: $ ls -Z /usr/sbin/opendmarc -rwxr-xr-x. root root system_u:object_r:dkim_milter_exec_t:s0 /usr/sbin/opendmarc $ ls -Z /var/run/opendmarc /var/spool/opendmarc -rw-rw----. opendmarc mail unconfined_u:object_r:dkim_milter_data_t:s0 opendmarc.dat When sending mail I no longer see any AVCs in enforced or in permissive mode in /var/log/audit/audit.log. Please note that I could only test it with opendmarc using a socket. I added to Fedora
