anyone know of a mail client that can filter on IMAP msg body?

[Net Llama!]

I'm getting drowned at work with nearly 5000 (yes, 5000) new emails each 
day.  Its reached the point of being ridiculous, and I need to find an 
email client that can reliably filter based on the content of the body of 
the messages (rather than just the headers).  The added twist is that this 
needs to work for an IMAP server (rather than POP).  Thunderbird claims to 
be able to do this, yet it flat out doesn't work (and others have reported 
similar problems).

Is anyone actually getting this to work (rather than theoretically 
thinking it might work) with any mail client?
