Hello-
And the plot thickens as well..

Evidently the email denied by SELinux eventually gets out on the network anyway through 
sendmail. The denial only defers the mail, so around ten minutes later the mail is sent again-
successfully however, due to sendmail making it's own request.

Here are the logs, grepping for the same set of timestamps and mail id's-
