we wish to transfer mail system from sendmail to zimbra mail. we have comodo certificate in send mail. we want to move it to zimbra server.
the same domain name , but the hostname of the server different . is it possible to that. and if it possibe how do deploy that
You should be able to export the private-key and certificate from the sendmail system, and import that in the zimbra server.
Here is a link to an example:
