Setting up a spamsafe Postfix server

I am currently in the process of upgrading my webserver to Debian Etch. In the past I have been using Debian Sarge with Plesk as an administration desktop. Plesk is very convenient, but it is also a memory hog and a performance killer, so I decided to go on without a web based administration tool and configure every service manually. This has the advantage that the system will be more secure and easier to update. The downside is a little bit more work in the beginning. During the next couple of postings I will document the configuration of the various services I have running on that server.

In this first post I will start with the mail service for which I choose the Postfix daemon together with policyd-weight for spam filtering and Dovecot as an IMAP and POP3 server. Authentication will be done with the SASL daemon against the standard user database.
