Description of problem:
SELinux is preventing sendmail from 'read' accesses on the file cmd.

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

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