fetchmail complaining about GoDaddy SSL certificate

Update: I don't think this fixed the problem

I was getting this every time I ran fetchmail.

fetchmail: Server certificate verification error: unable to get local issuer certificate
fetchmail: Broken certification chain at: /C=US/ST=Arizona/L=Scottsdale/O=GoDaddy.com, Inc./OU=http://certs.godaddy.com/repository//CN=Go Daddy Secure Certificate Authority - G2
fetchmail: This could mean that the server did not provide the intermediate CA's certificate(s), which is nothing fetchmail could do anything about.  For details, please see the README.SSL-SERVER document that ships with fetchmail.
fetchmail: This could mean that the root CA's signing certificate is not in the trusted CA certificate location, or that c_rehash needs to be run on the certificate directory. For details, please see the documentation of --sslcertpath and --sslcertfile in the manual page.
fetchmail: Server certificate verification error: certificate not trusted
fetchmail: Server certificate verification error: unable to verify the first certificate
fetchmail: Warning: the connection is insecure, continuing anyway. (Better use --sslcertck)

I appear to have fixed it by running:

sudo c_rehash

I found this by reading the documentation on --sslcertpath in the fetchmail man page. (As the error message told me to...)
