WD> Fidonet is not about BBSs though BBSs can use it to link-up. Hence my

His question was specific to his BBS running Renegade so jumping in about something else isn't beneficial and only serves to create confusion.

(Fidonet was absolutely created with the sole purpose of networking bulletin board systems together.  I was there.  It has evolved since then but that was its entire purpose. https://en.wikipedia.org/wiki/FidoNet)

 WD> The original question was "So is it the mailer or the BBS that handles
 WD> MSGIDs?"  

MSGID/REPLYID does not come from the mailer.  It needs to come from the reader client (whatever that may be).  The reader client is the only thing that knows what messages are replies to other messages, and as such its the only thing that can properly assign REPLYIDs.  The MSGID itself can either come from the BBS or the tosser.

This is nothing new, its how every BBS or client/reader works that support these systems properly, because thats how it has to work.

If he wanted to have a full MSGID/REPLYID and thread tracking like he may be used to seeing in Mystic and Synchronet, then it must be done by Renegade and its proprietary .MSG tosser in his setup's case.

... Some people have no idea what they're doing, and are really good at it!
