run script shell on receipt

[RudySixOw]

Hello, Sorry for my bad English. I come back with a question that I have already asked and for which I think I have found but in fact no ...

I want to trigger a shell script according to different rules. I did various tests with sieve but without success. Do you have a solution or a start to get there?

Thank you very much in advance.

I think there is no module in /usr/lib/dovecot/sieve/ or /usr/lib/dovecot/modules/sieve/ like sieve-execute
