[SOLVED] Adding a disclaimer (footer)

[civilwar]

I follow the instructions stated in Adding a disclaimer (altermime) or footer - Zimbra :: Wiki... but after i restarted using:

zmmtactl stop; zmmtaclt start

i got an error saying:

postfix/postfix-script: warning: not owned by root: /opt/zimbra/postfix-2.7.4.2z/conf/main.cf
postfix/postfix-script: warning: not owned by root: /opt/zimbra/postfix-2.7.4.2z/conf/master.cf
