Description of problem:
SELinux is preventing /usr/bin/esmtp from 'read' accesses on the file /root/.esmtp_queue/ZOs0vFLQ/mail.

*****  Plugin restorecon (99.5 confidence) suggests   ************************

If you want to fix the label. 
/root/.esmtp_queue/ZOs0vFLQ/mail default label should be mail_home_rw_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /root/.esmtp_queue/ZOs0vFLQ/mail

*****  Plugin catchall (1.49 confidence) suggests   **************************

If you believe that esmtp should be allowed read access on the mail 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 esmtp /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
