Description of problem:
SELinux is preventing mktemp from 'write' accesses on the directory /.esmtp_queue.

*****  Plugin catchall_labels (83.8 confidence) suggests   *******************

If you want to allow mktemp to have write access on the .esmtp_queue directory
Then you need to change the label on /.esmtp_queue
Do
# semanage fcontext -a -t FILE_TYPE '/.esmtp_queue'
where FILE_TYPE is one of the following: device_t, fsdaemon_tmp_t, fsdaemon_var_lib_t, fsdaemon_var_run_t, tmp_t, var_run_t.
Then execute:
restorecon -v '/.esmtp_queue'


*****  Plugin catchall (17.1 confidence) suggests   **************************

If you believe that mktemp should be allowed write access on the .esmtp_queue directory 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 'mktemp' --raw | audit2allow -M my-mktemp
# semodule -X 300 -i my-mktemp.pp
