So, going back to mid-November (p.73 on this thread) I was having trouble with the security certificate when trying to connect to email. This kind of went away by itself, but now the problem is back. To recap, I get the following message when trying to synch with my Sensation (with standard ROM) with my Xtra email account:

   Security warning
   There are problems with the security certificate for this site.
   This certificate is not from a trusted authority.
   [Continue] [View] [Cancel]

I only get the message when synching the Xtra account – synching with Gmail, or any other type of account (e.g. Facebook, Twitter, LinkedIn, etc.) is fine. If I view the certificate details it says:

   This certificate is not from a trusted authority.
   Issued to:
      Common name: VeriSign Class 3 Public Primary Certification Authority – G5
      Organization: VeriSign Inc.
      Organizational unit: VeriSign Trust Network
   Issued by:
      Common name:
      Organization: VeriSign Inc.
      Organizational unit: VeriSign Class 3 Public Primary Certification Authority
   Validity:
      Issued on: 2006-11-08 13:00:00+1300
      Expires on: 2021-11-08 12:59:59+1300

I wondered whether the blank “common name” in the certificate details is the reason it appears to not be from a “trusted authority”, but that seems too obvious.

At my local suburban Telecom store on the weekend, a guy thought the solution was to delete the Xtra account and add it again. I deleted it but can't add it at all now because I get the warning message as soon as I enter the email address and password.

Can anyone give me a beginners guide to these security certificates? My initial thought was that it’s something at the Telecom end that my phone checks when trying to connect. But if that was the case, surely everybody with an Xtra account would be getting this error. And then, if it’s something at the phone end, why isn’t everyone with the standard ROM getting this error?

Any information or ideas would be gratefully appreciated. BadCam previously suggested resetting the phone. think this will help? I’m prepared to try pretty much anything at this point – my phone has been my primary means of accessing my email for the last few weeks so this is really frustrating.
