Addition self signed certs

[3RiversTechAdmin]

Hey everyone,

Here is the issue I am facing: My self signed certificate for zimbra of course references the machines hostname (ie. hostname.domainname.com). This is fine for users on the LAN; however, users on the outside (who are going to mail.domainname.com) are prompted by firefox and ie that there may be spoofing going on because the cert is made our for hostname.domainname.com and not mail.domainname.com. I could change the machines hostname, but for other reasons this is not an option. Can I make and additional cert for mail.domainname.com? Any suggestions? Thanks
