SELinux is preventing /usr/libexec/postfix/qmgr from map access on the file /usr/libexec/postfix/qmgr. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that qmgr should be allowed map access on the qmgr file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'qmgr' --raw | audit2allow -M my-qmgr # semodule -i my-qmgr.pp Additional Information: Source Context system_u:system_r:postfix_master_t:s0 Target Context system_u:object_r:postfix_qmgr_exec_t:s0 Target Objects /usr/libexec/postfix/qmgr [ file ] Source qmgr Source Path /usr/libexec/postfix/qmgr Port <Unknown> Host bkr-hv01-guest24.example.com Source RPM Packages postfix-2.10.1-7.el7.x86_64 Target RPM Packages postfix-2.10.1-7.el7.x86_64 Policy RPM selinux-policy-3.13.1-197.el7.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name bkr-hv01-guest24.example.com Platform Linux bkr-hv01-guest24.example.com 3.10.0-893.el7.x86_64 #1 SMP Thu May 24 21:37:14 UTC 2018 x86_64 x86_64 Alert Count 1 First Seen 2018-05-26 13:12:33 EDT Last Seen 2018-05-26 13:12:33 EDT Local ID a34337c7-66a0-417d-ae68-0256111c8d0a Raw Audit Messages type=AVC msg=audit(1527354753.983:49): avc: denied { map } for pid=1458 comm="qmgr" path="/usr/libexec/postfix/qmgr" dev="dm-0" ino=67618103 scontext=system_u:system_r:postfix_master_t:s0 tcontext=system_u:object_r:postfix_qmgr_exec_t:s0 tclass=file permissive=1 type=SYSCALL msg=audit(1527354753.983:49): arch=x86_64 syscall=execve success=yes exit=0 a0=5577b14f8270 a1=5577b14f8670 a2=5577b14f4180 a3=ffffffff items=0 ppid=1456 pid=1458 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=qmgr exe=/usr/libexec/postfix/qmgr subj=system_u:system_r:postfix_qmgr_t:s0 key=(null) Hash: qmgr,postfix_master_t,postfix_qmgr_exec_t,file,map
