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

Problem:

On ZCS v8.7 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.

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
