No, nc is just a dumb tool -- it knows nothing about IMAP or SSL.  You didn't
even get to the SSL handshake.  Your problem has nothing to do with the
interaction of client and server -- it's strictly a server problem.

ssl_ca is not analogous to Apache's SSLCertificateChainFile.  I believe "ssl_ca"
is used to validate clients (i.e. mutual authentication).
You ought to concatenate your intermediate CA chain certificates and
your public key into ssl_cert.


Also, anything enlinghtening  in the logs when ssl_verbose turned on?
