Drupal email was failing. SELinux Administration GUI to the rescue. All kinds of great settings including httpd_can_sendmail to get around SELinux restrictions. What I don't understand is why I was not seeing any log entries or alerts that SELinux was blocking this?

I've always had trouble with selinux. Don't get me wrong, security is very important and I try my best to get it right. However, I sometimes have trouble getting things just to work, and security can make it even more difficult. Is it not working because I haven't set it up correctly, or is the problem that I don't have the right access. It's true that security IS part of setting something up correctly, a VERY important part. However, I often have to remove any security restrictions to divide issues between functionality and access.
