Applied policy update. Now I see these occasionally. But by the time I try and see what the matter is the file is gone:

If you want to fix the label. /var/spool/postfix/active/9934A60C7D default label should be postfix_spool_t. Then you can run restorecon. Do # /sbin/restorecon -v /var/spool/postfix/active/9934A60C7D

If you believe that smtp should be allowed lock access on the 9934A60C7D 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: # grep smtp /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp
