filtering IMAP by message body?

[Lonni J Friedman]

Hopefully one of the gurus here can help with this one.  I reguarly
receive over 4000 (yes, 4000) pieces of non-spam email each day, via
an IMAP server.  I desperately need a means of filtering/sorting my
email based on the contents of the message body (rather than just the
header).  As far as I can tell, this isn't possible with thunderbird
when using IMAP (only POP).  Anyone know of any reliable means of
doing this with a different full-featured email client?
