You can use mime_header_checks and a WARN action to log each attachment
header. Noel Jones regularly posts an expression used to block
attachments having a certain file extension. You could use a slight
variation of that expression for your purposes. This method will at
least provide the number of attachments but not the size of each
attachment. The size of each message can on the other hand already
be found in the log.
