[imp] Flag for "Message has Attachments"

[cjdl01]

Hello,

We are having some issues with emails with attachments not being  
immediately identifiable.  I noticed that under "Flags", there is an  
option to flag emails with attachments with a certain color.  I have  
tested this, and it doesn't seem to be working.  I set the flag to  
purple, and neither existing messages, or new messages are getting  
flagged.

I'm using procmail with my filter instead of imap, is that why?  Is  
there any way to get this flagging working?  It works in all other  
respects as far as I can see...

My horde/imp are current on all packages (verified through pair just a  
moment ago).

Thank you!
