Sendmail & treatment rules for incoming messagges

[sbix]

Hi everybody,
I need to write a program/shell script activated by the reception of a mail from a specific user@host.
I could poll in a cyclic fashion the mailbox, but i'd prefer a sort of "event-driven" solution.
So I'd like to know if there's a way to write something like the Outlook Express rules, which executes something on the reception of a specific message from a specif user@host.
Any ideas?

I think you could do that by passing the mail through procmail
where you can define what you want

I do this with my Linux server and it works fine for me.
