We are and ISP that uses squirrel mail as our 
e-mail.  When our customers go to the website to view there mail they 
receive the follow screen shot.

      There is a problem with this website's security 
      certificate.

      The 
      security certificate presented by this website was not issued by a trusted 
      certificate authority.
      The security 
      certificate presented by this website has expired or is not yet 
      valid.
      The 
      security certificate presented by this website was issued for a different 
      website's address.

Security certificate problems may indicate an attempt to 
      fool you or intercept any data you send to the server. 

      We recommend that you close this webpage and do 
      not continue to this website.

          More 
            information

If you arrived at this page by clicking a link, check 
      the website address in the address bar to be sure that it is the address 
      you were expecting. 

When going to a website with an address such as 
      https://example.com, try adding the 'www' to the address, 
      https://www.example.com. 

      For more information, see "Certificate Errors" in 
      Internet Explorer Help.

How do we get this to stop.  Its frustrationg 
to the customer to see this and our older customers get scared and stop going to 
it and call us.  Is there a certificate that they can install that will 
cure this.

Thanks
Kevin
