When I try to go to the admin portion of Zimbra, this is what I get:

208.110.73.227:7071 uses an invalid security certificate.

The certificate is not trusted because it is self signed.
The certificate is only valid for mx1.seymourherald.com

My IT guy left to a great job and I don't know what is wrong. It's been working great for a couple of years.

HELP
