I have the Verisign certificate on my clients trusted root CAs, however I am

not able to get the SSL communication through. I believe this is because stunnel should send all the three certificates for authentication and I couldnt configure stunnel to send across all the three certificates.

Can anybody please help install all these certificates on stunnel.

Simply concatenate the certificates (in PEM format) in the file specified by "cert = ..." and supply the key of your server certificate either in the same file or in the file specified by "key = ...".
