You'll need to generate a new certificate for your imap server if you want to stop getting the "certificate expired" message. If you want to get rid of the "certificate belongs to localhost.localdomain" message as well, you'll need to ensure you generate the certificate using the correct name with which you connect to the server.

If you're also getting messages about the certificate being issued by an untrusted issuer, you'll want to either buy a cert, or just install the cert into your browser as a trusted CA.

Note: If this is coming for a mail server which is provided by your hosting provider, and the server is used for shared hosting, you may not be able to get rid of the "untrusted issuer" and "localhost.localdomain" messages, since not many web hosts actually install full certificates on their shared mail servers.

How do i generate this certificate i just used the one that came with the configuration?

Creating your own cert on a RedHat / Fedora / CentOS box is as simple as:

1. cd /usr/share/ssl/certs
2. make something.pem
3. mv something.pem dovecot.pem (or imapd.pem) depending on which imap server you are using.

If you're looking at some other distribution or imap server, you'll just need to google it up. There are plenty of links to configuring SSL support for imap all over the 'net.

Hope that helps.
