Certificate Errors - OS X 10.4

Older Macintosh computers running Tiger (10.4) with an outdated Apple Mail may not handle SSL correctly. If you are getting a Certificate warning for a known good Certificate each time you access your mail, you may need to disable SSL to stop the warnings. Disabling SSL will copy your email to and from your Mac in plain text. For an immediate fix, click Continue and you’ll successfully access your mail. Disabling SSL exposes your email while it is copied between your desktop and the email server. OlympusNet does not recommend disabling SSL and exposing email in plain text. For more information, refer to https://discussions.apple.com/thread/1504426?threadID=1504426&tstart=50
