Description of problem:
When running sendmail (provided by opensmtpd) from a cron job, permission is denied, resulting in an error like this:

sendmail: cannot create temporary file /var/spool/smtpd/offline/1739546283.XXXXXxumpB: Permission denied
SELinux is preventing /usr/sbin/smtpctl from 'write' accesses on the directory /var/spool/smtpd/offline/.

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

If you believe that smtpctl should be allowed write access on the  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
