Hello,

I have this setup :

mbox.grampet.com - mbox/store zimbra server with imap, smtp, mta, etc
mx.grampet.com - Zimbra proxy ONLY ( imap, pop3, smtp, http - proxy mode redirect )

The mbox server has an internal ip address and it's accessed only by the proxy server.

I installed on the proxy server ( mx ) my commercial certificates issued by Verisign.

When i go to https://mx.grampet.com with any browser, everything works fine.

When i try to setup an account with zimbra desktop, it gives me the following error :

Code:
Invalid or untrusted server SSL certificate (details)

mx.grampet.com presented a certificate that cannot be verified.
