Steps to fix permission and ownership of Postfix binaries manually due to bug on zmfixperm

---

Problem:

On ZCS v8.7.0[1,2] running "zmfixperms --verbose --extended" set incorrect permissions on postfix binraries.

Getting following errors with postfix related commands.

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

Solution

With the help of following commands we can set correct permission and ownership of 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
