[Mimedefang] Greylisting Question and Lost Input Channel

[Jeff Grossman]

I just set up Greylisting on my service and have a question about the log.
Is it normal for me to see these Lost Input Channel messages now?

If you notice, it only happens when I block a message from a DNSBL.  I block
those from within Sendmail directly.  Here is an entry where I block a piece
of mail from the access.db, and I don't have that Input channel message.
