use procmail - it's easy and actually works. you can do basically 
everything with procmail.

This question is off topic, dovecot is not SMTP agent.

use procmail and possibly formail to execute anything and optionally reply 
the result

man procmailrc
man procmailex
man formail

make sure procmail is actually executed on your mail system. depends of 
your MTA.
