Last Resort Host

Keywords: lastresort

The lastresort keyword is used to specify a host to connect to even when all other connection attempts fail. In effect this acts as an MX record of last resort. This is only useful on SMTP channels.

The keyword requires a single parameter specifying the name of the “system of last resort.” For example:

tcp_local single_sys smtp mx lastresort mailhub.siroe.com
TCP-DAEMON
