We have one server with multiple e-mail domains. I followed the directions here -

Administration Console and CLI Certificate Tools - Zimbra :: Wiki

Under the section for Single-Node Commercial Certificate. Everything goes great, until I get to the section of verifying my certificate, which is where I get an error. It verifies my key against the private key and they match. Then I get an invalid certificate message stating "error 20 at 0 depth lookup:unable to get local issuer certificate".

I am running Release 6.0.5_GA_2213.UBUNTU8_64 UBUNTU8_64 NETWORK edition - I did the CSR through Digicert for Tomcat, not sure if that is the wrong platform or may be the issue.

Thanks in advance
