SELinux is preventing /usr/libexec/dovecot/dovecot-lda from 'read' accesses on the fifo_file fifo_file. ***** Plugin leaks (50.5 confidence) suggests ****************************** If you want to ignore dovecot-lda trying to read access the fifo_file fifo_file, because you believe it should not need this access. Then you should report this as a bug. You can generate a local policy module to dontaudit this access. Do # grep /usr/libexec/dovecot/dovecot-lda /var/log/audit/audit.log | audit2allow -D -M mypol # semodule -i mypol.pp ***** Plugin catchall (50.5 confidence) suggests *************************** If you believe that dovecot-lda should be allowed read access on the fifo_file fifo_file by default. Then you should report this as a bug. You can generate a local policy module to allow this access.
