I have a nagging issue with Thunderbird. It keeps giving me a hard time with certificates. It just doesn't seems to handle them to well.
I use IMAP, and my hosting is Cpanel stuff. I also use the plugin Remember Mismatched Domains but still, I always get this error message:
[You have received an invalid certificate. Please contact the server administrator or email correspondent and give them the following information:
Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number.]
I verified RMD (Remember Mismatched Domain), cleaned it. I got to Thunderbird Certificate Manager verified that everything was OK. I erased the "faulty certificate" and restarted Thunderbird. Erasing the "faulty certificate" is the only thing that make it works but only for a time and it starts behaving badly shortly after.
Does anyone know if it's a (known) bug within Thunderbird?
Does anyone have the same issue as mine and found a reliable solution to it?
I'm eager to hear from you.
