*           NOTE - If you are using a self-signed server certificate with
 *           either imap/ssl, imap/tls, pop3/ssl, or pop3/tls, you MUST add
 *           '/novalidate-cert' to the end of the protocol string. For imap,
 *           this would be 'imap/ssl/novalidate-cert' or
 *           'imap/tls/novalidate-cert', and for pop3 it would be
 *           'pop3/ssl/novalidate-cert' or 'pop3/tls/novalidate-cert'. This
 *           is necessary to tell c-client not to complain about the lack of
 *           a valid CA on the certificate.
