i finally made it in the intent of adding an autoresponder to my postfix server, and it works, but....it creates problems with dovecot!
transport: myu...@mydomain.com vacation
when i send a message to this account, i get the autoreply (this is ok) but the receiving account doesn't receive the mail i send (i think because the autoresponder plugin gets it and dovecot doesn't get the email).
