Steps to fix permission and ownership of Postfix binaries

---

Problem

While normally 'zmfixperms' is the preferred method to do this, on ZCS v8.7.0[1,2] running "zmfixperms --verbose --extended" sets incorrect permissions to the Postfix binaries.

The following errors are seen when this is the case:

Connect to the Postfix showq service: Permission denied
postqueue: fatal: Connect to the Postfix showq service: Permission denied

Solution

With the help of the following commands, we can set the correct permission and ownership of the Postfix binaries.

[Run as ROOT]

chown root:postdrop /opt/zimbra/common/sbin/postqueue
chown root:postdrop /opt/zimbra/common/sbin/postdrop
chown root:root /opt/zimbra/common/libexec/ -R     
chmod 755 /opt/zimbra/common/sbin/postqueue   
chmod 755 /opt/zimbra/common/sbin/postdrop  
chmod g+s /opt/zimbra/common/sbin/postqueue   
chmod g+s /opt/zimbra/common/sbin/postdrop 

This bug has been fixed in ZCS v8.7.3
