[nos-bbs] DUPES and staggered forwarding

[Langelaar]

    and now I finally understand why the BID is stored in the history by 
smtpserv,
    and why BID is even in the smtp server code for that matter. The 
messages
    coming in via forwarding are internally delivered by smtp, and that 
is when
    the BID is actually saved to history, NOT when the forwarding is 
completed,
    and there is always a bit of time between the two events :|

    So how to deal with that ? working on it ... in the meantime, 
stagger your
    forwards ? I think this came up quite a few years ago actually, I 
honestly
    don't remember anymore, might even have been posted to NOS-BBS ...
