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.
