Translations:Mailfiltering Gateway/6/en

In this setup applications with good security records and readable configuration files have been chosen. The email MTA is postfix which has a good security record and is fairly easy to setup right. Postfix will listen normally on port 25 for incoming mail. Upon reception it will forward it to Amavisd-new on port 10024. Amavisd-new will then filter the mail through different filters before passing the mail back to Postfix on port 10025 which in turn will forward the mail to the next mail server.
