sendEmail - default of SSL_verify_mode of SSL_VERIFY_NONE for client is deprecated

*******************************************************************
 Using the default of SSL_verify_mode of SSL_VERIFY_NONE for client
 is deprecated! Please set SSL_verify_mode to SSL_VERIFY_PEER
 possibly with SSL_ca_file|SSL_ca_path for verification.
 If you really don't want to verify the certificate and keep the
 connection open to Man-In-The-Middle attacks please set
 SSL_verify_mode explicitly to SSL_VERIFY_NONE in your application.

    # for now we keep the default of SSL_VERIFY_NONE but complain, if
    # somebody uses this implicit default
    # SSL_verify_mode => undef,  # set to undef to enable secure default
