If your BCC address somehow causes another SMTP session back into the
machine, then yes this might happen.  The only way I can think of it
doing this is if the -B address is a generic one (say address@hidden)
that routes to a "master" smtp server, which then rewrites the address
to a local address (address@hidden) that happens to route
back to the first server, which re-milters the mail.  Addresses that
resolve to local accounts, or ones that resolve to remote accounts they
stay remote, shouldn't cause problems.

I recommend adding all internal SMTP servers to the -i list, so
internally-routed mail isn't checked.  Also speeds up routing, because
a message is only checked once as it enters the system.

Which behavior?  Auto-ignoring mail sent to the -B address?  That's a
good idea.
