Adding an SSL Certificate to Eudora
With some versions of Eudora, you may receive an error message that says something like this:
SSL Negotiation Failed: Certificate Error: Cert Chain not trusted. Try adding this certificate to your certificate database for SSL to succeed.This happens because Eudora has not been updated for a long time, and does not include modern "SSL root certificates" needed to encrypt your e-mail messages.
You should be able to use the instructions below to add the necessary SSL certificate to Eudora.
1. Open the Eudora options window.
Click Tools, then Options from the menu bar.
2. The Options window appears.
Click Sending Mail in the category list, then click the Last SSL Info button.
3. The Eudora SSL Connection Information Manager window appears.
Click Certificate Information Manager.
4. The Certificate Information Manager appears.
Make sure that the mail.tigertech.net certificate (located under server certificates) is highlighted, then click Add To Trusted.
The certificate will be added and appear under the User Trusted Certificates
Click Done to close the Certificate Information Manager window, then OK to close the Eudora SSL Connection Information Manager and OK to close the Options window.
Eudora should now be fully configured. Try sending yourself a test message.
