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. Incoming Messages ----------------- 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.
