Android handsets do not recognise GoDaddy’s SSL certificates
I’ve just spent some time to figure out why my Android mobile can’t connect to certain mail account (both IMAP and SMTP, delivered over SSL and TLS respectively). The problem is that SSL certificates were signed by GoDaddy, which is not trusted CA on Android platform. The standard mail application does not allow you to accept untrusted certificates, so the easiest workaround was to use other email client. Came across K-9 Mail, which looks and feels way better than the one that comes shipped with the phone (and does have an option to accept untrusted certificate).
