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