TJOIN(8)

NAME
tjoin - Unrolls the Application Relays.

SYNOPSIS
tjoin [-d] local-domain-name channel-names... < input-file

DESCRIPTION
Tjoin is a lexical program that is used to construct the channel table residing in the PP table directory.

Tjoin performs a number of transformations on the data.

It firstly fills in all missing channels. If mail to one host must first be sent to another host, tjoin will expand this to the correct form and fill in the appropriate channel.

Secondly, it removes references to the local domain name specified in the first parameter.

Thirdly, it sorts the hosts with multiple channels into the preferred order given on the command line. The order is the same order as the channel-names parameters.

Tjoin responds to several flags.

-d  Prefer direct routes to hosts over the ordering given on the command line. E.g. if there are two channels to a host, and one is direct and the other goes via an intermediary always prrefer the first one. This should be the nromal setting.

-c  Produce a more complex output, this may save a little space, but is probably not worth while and is untested.

-r  put route entries in the output. This option should not be used other than for debuging

The normal procedure is to run with the -d flag enabled.
