Brad is correct, particularly about diagnosis. I just want to add a
couple of ideas.

If Mailman's content filtering removes ALL the MIME parts so none
remain, the post will be handled according to filter_action; it won't
go to the list. If content filtering is removing the body, there must
be some other part which may be blank but is not removed for the
result to go to the list.

Another possibility to consider is that the message may be an HTML or
other rich text format message which is reaching the list and which
has (for example) white text on a white background. If this is the
case, the "blank" message body may be sizable to the point that it has
a scroll bar, but still "blank". You may be able to select the "blank"
text, copy it and paste it into a plain text editor and see it that

This latter situation comes about when someone has their own MUA set
for "rich text" with a default background color of say black and an
explicit font color of white. Then, when the white on black message is
viewed by someone whose MUA backgrownd color is white, she sees the
white on white "blank" message.
