I'm trying to set up Gmail using a desktop client, via IMAP. It works, except that my client is complaining about the SSL cert:

Issuer: CN=Google Internet Authority,O=Google Inc,C=US
Subject: CN=imap.gmail.com,O=Google Inc,L=Mountain View,ST=California,C=US
Fingerprint: f4:3c:f0:30:6a:03:d4:5b:c8:5b:6e:11:ed:19:1d:a6
Signature: BAD

It seems odd that Google would use a self signed cert here, but a cert signed by Thawte on their website. The Google CA is not in my /etc/ssl/certs. Does anyone know if this is the correct cert? Is my trusted CA list just hopelessly out of date?

  • What client do you use? I'm using both Mail.app and Notify and I didn't had any problems with the certificates.

The IMAP cert is signed by a "Google Internet Authority" cert which is in turn signed by Equifax your client is not following the certificate chain of trust properly.

    Or the client doesn't trust the "Equifax" root cert in question.
