Color messages in the index view dynamically

[dm1581 at gmail.com]

Hi all,

I have some messages with a subject line containing the "due:[here
goes some date]" text. I want mutt to color these messages differently
and dynamically (at every opening or refreshing the mailbox) according
to whether the date in the subject is in the past or the future
compared with the current date.
Is it possible to accomplish?

It would be nice to enchance the "todo.txt" approach with the "to-do
mailbox" advantages :-)

Best,
