Blank Message Rule

[Stuart Johnston]

I get a lot of messages that are completely blank - no subject, no body. 
 I want to create a rule to match these messages.  I started with this:

rawbody __HAS_BODY  /\S/
meta LOCAL_EMPTY_MESSAGE  (!__HAS_SUBJECT && !__HAS_BODY)
(although I think the __HAS_SUBJECT is redundant)
The problem is that this also matches messages that consist only of an 
attachment and should be considered valid (think photos sent from cell 
phones).

Is there any way to check against the full message body before 
attachments are processed?  Or other suggestions?

Thanks,
