How can this happen? It's getting denied, but not appearing in either the
audit log or the messages file. Running Centos 6 fully updated, php
(drupal) inside of httpd tries to send mail via postfix (postdrop).
When I have setenforce 0, the mail goes through. No errors in any logs
(audit.log, error_log, messages)
When I have setenforce 1, the mail gets blocked. I get this message in
httpd error_log:
sendmail: fatal: execvp /usr/sbin/postdrop: Permission
denied
sendmail: warning: command "/usr/sbin/postdrop -r" exited with status 1
sendmail: fatal: email(a)example.com(48): unable to execute /usr/sbin/postdrop
-r: Success
I have auditd running. In fact, I regularly use audit2allow to create allow
policies on this machine. So I can confidently say normally my selinux
denials get logged in the audit.log. I am at a loss to think of any reason
this particular failure is not getting logged the same way my other error
messages usually get logged.
I believe I can write a custom allow script by hand, but I believe I
probably shouldn't, or if I try, it will fail for some reason.
Thanks for your help...
