Description of problem:
SELinux is preventing sendmail from write, open access on the file /.esmtp_queue/pqX23o0a/cmd.

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

If you want to fix the label. 
/.esmtp_queue/pqX23o0a/cmd default label should be default_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /.esmtp_queue/pqX23o0a/cmd

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

If you believe that sendmail should be allowed write open 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
