Description of problem:
After upgrading from fedora 26 to fedora 27.
SELinux is preventing sendmail from 'open' accesses on the directory /root/.esmtp_queue.

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

If you believe that sendmail should be allowed open 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 'sendmail' --raw | audit2allow -M my-sendmail
# semodule -X 300 -i my-sendmail.pp
