So something is happening in the processing pipeline after the
'Moderate' handler which holds non-member posts. What is in Mailman's
logs - particularly 'error' and 'vette'?

A programmed discard will produce a "Message discarded, msgid: ..."
message in the vette log. The only ones that occur after Moderate are
in Scrubber and MimeDel. Since this occurs with content filtering off,
it's not MimeDel. It's not likely to be Scrubber either since
Scrubber's discard only occurs with single part HTML messages, not
with messages with attachments.

This leaves some exception occurring in processing messages with
attachments. This shoud produce an error message and traceback in the
error log.
