Presumably, as Joseph shows with his nc call, imap calls are to ServerName mail.privustech.com.

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 = required ssl_cert =

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?
