Hi Stephen,

I would call it a design flaw. ;)

Rob explained it to me as follows:

"The duplicate message checking occurs in the Synchronet Message Base (SMB)
library, which is not specific to FidoNet or any other networking technology.
So whether a message is imported via QWK, NNTP, SMTP, PostLink, FTN, or
whatever-future-networking-technology, it is subjected to the same database of
hashes to detect duplicates.

When an FTN message packet is processed by SBBSecho but the message is not
imported into a local message base (e.g. pass-through area or passing between
up/downlinks), the SMB library is thus not involved (the message would go
straight from one FTN packet to another FTN packet), never touching a
Synchronet message base."

So as I understand it the dupe checking only happens when messages are imported
into the message base. But by then the message is already tossed/send to all
connected links...

Bye, Wilfred.
