    Set Up Postfix For Relaying Emails Through Another Mailserver This short guide shows how you can set up Postfix to relay emails through another mailserver. This can be useful if you run a Postfix mailserver in your local network and have a dynamic IP address because most dynamic IP addresses are blacklisted today. By relaying your emails through another mailserver that is hosted on a static IP address in a data center (e.g. your ISP's mailserver) you can prevent your emails from being categorized as spam.

  • Virtual Users And Domains With Postfix, Courier And MySQL (CentOS 5.1)

    apache Author: Falko TimmeTags: , , Comments: 19

    Virtual Users And Domains With Postfix, Courier And MySQL (CentOS 5.1) This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I'll show how to patch your Postfix appropriately). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses.

    Full Mail Server Solution w/ Virtual Domains & Users (Debian Etch, Postfix, MySQL, DoveCot, DSpam, ClamAV, Postgrey, RBL) This guide describes how to set up a full email solution in Debian Linux (all code is from Debian Etch).  I was asked to design a secure, scalable, portable solution for a small company.  While the guide references many 'servers', the company only had 4 physical machines, Xen was used to virtualize the entire solution.  That particular aspect of the system is not discussed in this guide, although I will try to get it into the next revision.

  • How To Implement SPF In Postfix

    Author: Falko TimmeTags: , Comments: 16

    How To Implement SPF In Postfix This tutorial shows how to implement SPF (Sender Policy Framework) in a Postfix 2.x installation. The Sender Policy Framework is an open standard specifying a technical method to prevent sender address forgery. There are lots of SPF extensions and patches available for Postfix, but most require that you recompile Postfix. Therefore we will install the postfix-policyd-spf-perl package from openspf.org which is a Perl package and can be implemented in existing Postfix installations (no Postfix compilation required).
