I was worried about this. So, at this point, I don't wish to send 10
emails, just because i have 10 recipients in Bcc:. So, I guess I'll just
ignore Bcc: altogether.

in two penny blue I chose to split the to list and send one message per stamp ( iirc). compared to the cost of stamping, sending 1 recipient copies is rather small. this choice also made the outgoing message processing logic simpler. look in the headers. if I remember what I did 2+ years ago correctly, you should see a stamp on the bcc copy I sent you and no headers (or minimal) on the mailing list one.

two penny blue works and is mostly real world ready. 3 bugs that I haven't had time to fix: 1) training causes a "weird" score distribution. too many messages end up between the red fence and 0. 2) if anyone uses the default address on the "my addreses" list, it kills off filtering for those listing non-default addresses in the same domain.
3) searching (from dumpster) causes sql exception and killing filter daemon.

but other than that it is in really great shape :-)
