Hmm, let's see... it means the SSL cert you're using with Postfix has expired! :) It is beyond its valid lifetime. You should get a new one -- either self-signed from your organization's internal CA or (more likely) from your commercial CA.

Really Thanks, but sorry i don't understand any thing.
I'm the owner for that server and I'm the admin too.

This will be a good time to learn and document the procedures within your organization for obtaining and managing SSL certificates. Does that ring a bell with you? If you're totally on your own, you are going to have to do some work from scratch (including possibly securing funding for things like cert renewals.)
