Hello

Apparently my original question was completely asinine...


I suppose what I really need help with is creating a CA that is somehow
"chained" to a CA from another server ???


+CA - main server
|
+--CA - intermediate server
|
+----Cert signed by intermediate server, used to sign an email


Let's say I have an email server on a host completely different from
either server listed above. The mail server listens for incoming smtp
mail, only processing messages that were signed by a "valid" CA above.

1) Does the client cert contain any information linking back to the main
top level server?

2) (OR) Do I have to maintain a list of all the "valid" CA's on the mail
server?

3) How can I create a CA on the intermediate server that is "signed" by
the main server? This is kind-of like an Entrust cert that is below
"GTE" in a CA chain.

In my Internet searches for Chained CA's I only retrieve results to
other sites that have chained CA's and how to import the chain of trust
in the browser/server, etc. but I can't find any documentation with
regards to actually creating them.

Thanks!
