How To Implement Domainkeys In Postfix Using dk-milter
Author: topdog • Tags: antivirus, centos, postfix • Comments: 8How To Implement Domainkeys In Postfix Using dk-milter Domainkeys is "DomainKeys is a method of e-mail authentication. Unlike some other methods, it offers almost end-to-end integrity from a signing to a verifying Mail Transfer Agent (MTA). In most cases the signing MTA acts on behalf of the sender, and the verifying MTA on behalf of the receiver. DomainKeys is specified in Historic RFC 4870, which is obsoleted by Standards Track RFC 4871, DomainKeys Identified Mail (DKIM) Signatures." according to the wikipedia. So why a how to on it when there is DKIM ? Well domainkeys is still actively being used and is more widely deployed than DKIM, the developer Yahoo still uses it to sign and verify mail although they are contributers to the DKIM standard.

Virtual Users And Domains With Postfix, Courier And MySQL (CentOS 5.1)
Author: Falko Timme •
Tags: antivirus, centos, postfix •
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.

Therefore this tutorial explains how you can create and install your own Courier rpm packages from the sources, and I provide download links for my Courier rpm packages that I compiled on Fedora 8 (i386) so that you can save some time.
