Public bug reported:
When performing tls authentication to an SMTP server which has an
unverified OCSP record, as is the case with all new StartSSL
certificates for about 24hrs, thunderbird reports the following error:
Sending of the message failed.
The message could not be sent using Outgoing server (SMTP) mail.example.com for
an unknown reason. Please verify that your Outgoing server (SMTP) settings are
correct and try again.
This is very confusing and impossible to troubleshoot. It should report
"The server's SSL certificate failed OCSP validation.
To reproduce, go get a startssl certificate, add it to an smtp server,
connect with thunderbird, receive error. In settings, disable ocsp
verification, and it connects with no error and behaves as expected.
