Gateways
|
|
|
|
|
--------
|

|
|
|
|
|
|
|
Gatewaying between Fidonet and other networks seems to be the latest feature
|
|
|
|
|
which hopefully brings more benefits to the users of each network. But there
|
|
|
|
|
are some real problems with gatewaying and doing "transparent" replies.
|
|
|
|
|
This proposal should allow for almost totally transparent gateways but requires
|
|
|
|
|
the co-operation of BBS software writers to support this following protocol.

When a message is entered into fidonet from another network it will be entering
|
|
|
|
|
through one machine (say 1/2). The userid on the other network may not match
|
|
|
|
|
very will with the 2 word 36 character userid on Fidonet. So the following is
|
|
|
|
|
done to store away the proper userid of the sender.
|
|
|
|
|
|
|
|
|
|
Two (2) lines are added to the message (usually at the top of the text portion
|
|
|
|
|
hidden by the infamous ^A KLUDGE).
|
|
|
|
|
|
|
|
|
|
^AREPLYADDR .....\r
|
|
|
|
|
|
|
|
|
|
which signifies the FULL userid of the person on the other network. The first
|
|
|
|
|
36 characters or the full userid if less than 36 characters long, are stored
|
|
|
|
|
in the FROM field of the message header. When replies are done they use a
|
|
|
|
|
second line of the following form.
|
|
|
|
|
|
|
|
|
|
^REPLYTO zone:net/node firstname lastname
|
|
|
|
|
|
|
|
|
|
which is used to signify the "userid" which mail destined to this other network
|
|
|
|
|
must be sent to and on which machine that userids resides. Replies are sent
|
|
|
|
|
to this zone:net/node and userid with the first line of the message being
|
|
|
|
|
changed into 'TO: ....' where .... is the FULL userid from the ^AREPLYADDR
|
|
|
|
|
line.
