[APG Public List] Messages with attachments unwelcome

[Peter J Seymour]

I am finding that most if not all of the messages coming through the new APG public 
mailing list have all their content in an attachment. Previously, most if not all messages 
did not have an attachment, but had the content in the main body.
This plethora of attachments is a real inconvenience. Is there an option that can be set, 
either for the whole list or just for individual users, to deselect this "content as 
attachment"?
Thanks
Peter
