I ran into a very similar problem on our web servers but wanted to keep SELinux set to enforcing mode. This Red Hat link provides a solution. You need a Red Hat portal account to read it.


Writing a Custom SELinux Policy


In a nutshell, these commands will help (substitute “sendmail” for [application]:


grep [application] /var/log/audit/audit.log | audit2allow -R -M my[application]


semodule -i my[application].pp

Subject: sendmail and SELinux


Hello Support,

I ran CGP on the same box centos 7 with a php application and when SELinux is enabled I can’t send emails from php through sendmail replacement from CGP.

The config in php.ini is fine and the appropriate link has been created in /usr/sbin/sendmail=> /opt/CommuniGate/sendmail, the context of the /opt/CommuniGate/sendmail is “sendmail_exec_t” just like the original application sendmail.postfix . I think it maybe another SELinux context I am missing , probably related to the new path where sendmail is now.

If anyone can point me in the right direction, I really appreciate it.
