We're looking at embedding a Postfix mail setup into an existing web (php / mysql) product so that it can offer inbuilt email send/recieve support along with mail account management (its a CRM).
Ideally I don't want to be polling via POP3 or IMAP every so often to see if an account has new mail - is there a way to configure postfix so that it runs a script every time it receives a new mail?
That way, as long as it includes details of the recipient, I could setup a notification for the user within the CRM and not have to constantly poll the mail accounts.
