I have setup an e-mail server on my box but when I try to connect by using an E-mail client (Thunderbird). I get an issue with SMTP saying:
"Server Certification Expired
"example.com.com" is a site that uses a security certificate to encrypted data during transmission, but its certificate expired on 8/16/2008 8:55 PM.
Note: My site is example.com not "example.com.com".
How can I fix this issue?
