Title: A note on sendmail and SELinux in Red Hat Enterprise Linux
Post by: manyon on August 10, 2011, 09:59:34 PM
Hi everyone,
  when installing SMF 2.0 on RHEL6 recently, I found that emails were not being sent, with the error
Code: [Select]
sendmail: fatal: chdir /var/spool/postfix: Permission deniedshowing up in /var/log/httpd/error_log.  This was caused by the apache user not having SELinux permission to send email. This could also occur on other distributions which use SELinux (particularly Fedora and CentOS, but possibly others as well), if it is set to "Enforcing".

You can check this by using
Code: [Select]
/usr/sbin/getsebool httpd_can_sendmailwhich will report
Code: [Select]
httpd_can_sendmail --> {on|off}and if it is off, you can turn it on using
Code: [Select]
sudo setsebool -P httpd_can_sendmail 1with the "-P" for persistent (across reboots).

Hope this helps someone!

Great post, thanks.

Same solution goes for Scientific Linux.

I tried to use this to fix the issue I am having with the forum not sending out email.  The command reply is setsebool: SELinux is disabled.  Is there anything else I can try to get this to work?

If SELinux is disabled, then this doesn't apply to you. Start a new support topic with an explanation on your issue.

Upgraded to CentOS 7, and the same solution works there too.
