Your websites fingerprint changed and your’re getting a SSL error message
I had a little issue with my self hosted mail lately when the fingerprint of my domain changed. Suddenly I didn’t received any e-mail anymore. After checking the logs I’ve seen a message that said something along the lines of SSL3_GET_SERVER_CERTIFICATE validation failed error.
I’d like to show you how I’ve fixed that.
By issuing fetchmail -v command against your domain name you will get the fingerprint information. You might need to enter your passwort for that.
$ fetchmail -v mail.yourdomain.com
In the output search for the line fingerprint: and copy the hex string. Now edit /etc/fetchmailrc and add the following line, if not already there:
$ ssl sslfingerprint "xx:xx:..."
Now restart fetchmail:
$ service fetchmail restart
Your mail should now pour in again. 🙂
