TCP/IP-channel-specific options: BANNER_REVERSE_HOST (boolean)

This option applies to the SMTP/LMTP server. It defaults to 0 (false). If set to 1 (true), when a connection is accepted a reverse DNS lookup is performed on the local host's IP address. if a result is returned it becomes the name used in the server's 220 banner. This value takes precedence over any BANNER_HOST value as well as any local_host_alias value.
