SELinux is preventing /usr/sbin/sendmail.sendmail from using the 'execstack' accesses on a process.

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

If you believe that sendmail.sendmail should be allowed execstack access on processes labeled system_mail_t 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
