Ok going from 6.0.2 -> 6.0.5 NE on RHEL 4.x (Yes I know that the next major version won’t support 4.x) and I was hoping for a nice smooth upgrade, the previous SSL Comercial cert problems now showing as fixed in the bugtracker, however at the end of the process and I’m getting the same “Expired Cert” warning messages from email clients and the like….
So as root
cd /opt/zimbra/ssl/zimbra
/opt/zimbra/bin/zmcertmgr deploycrt comm commercial.6.0.2/commercial/commercial.crt commercial.6.0.2/commercial/commercial_ca.crt
Restart the services using ZMProv and all is good.
