Hi Someone who has been running the procmail that could give a hand, there is no way that I work with postfix, I know I'm doing wrong. /etc/procmailrc? Because you must go to the configuration file? Example how to make incoming messages are not duplicated or triple, etc.. To work on cosets with Postfix I activated this mailbox_command = procmail-a "$ EXTENSION" but nothing My postfix uses Maildir mail users are in / home / user / Maildir /
