[Mimedefang] DSN discarded by MIMEDefang?

[Ferdinand Goldmann]

Hello,

I'm experiencing an odd problem here. Our MIMEDefang installation
is configured to discard (with a pretty much out of the stock filter)
messages of type message/partial. So far, so good.

When a message from an outside domain is filtered, a DSN is received by
the sending user/machine as expected. But when a user from one of our
domains sends mail, so that the DSN has to pass through the same
MX MIMEDefang is running on, it seems to be discarded by the filter:

Beginning from here, it looks as if the DSN is discarded by MIMEDefang himself?

Well, I'm rather puzzled ... has anyone experienced this before?

Kind regards, thanks in advance for any hints!
