Yeah, been doing this per your instruction since the other day, which is why
you're probably super happy with me  =)

Well, the thing is, it's not my outbound packets that are being processed as
Netmail by the BBS, it's incoming packets, specifically just BattleNet's.
It never processes yours as Netmail. And I don't understand why or how. I've
setup events and a batch file to isolate *all* game packets now before any
echomail processing is done to a separate directory and it's still happening,
which means I have to reset my Netmail messages every day since there's a
couple hundred netmails I can't access each day.

Nothing points to that game packet directory except that one batch file which
moves them, and the games themselves, which only use them as an INBOUND
directory. As soon as packets are created on my end they're tossed into a
FileBox directory where they sit until every 60 minutes my interval event runs
my ibbs.bat file, which processes all of the packets in the PACKETS
directory, spits out outbound packets to the FileBox directories, creates
custom semaphores, which calls the two semaphore events (depending on which
semaphore it creates).

Absolutely nothing should be processing any packets before the game packets
are moved, so I'm stumped as to how or why it's happening.
