Description of problem:
SELinux is preventing touch from write, open access on the file /root/.esmtp_queue/.lk02873casuslap.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that touch should be allowed write open access on the .lk02873casuslap 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 'touch' --raw | audit2allow -M my-touch
# semodule -X 300 -i my-touch.pp
