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. falko Tue, 05 Feb 2008 12:36:44 GMT http://www.howtoforge.com/how-to-install-and-configure-mailman-with-postfix-on-debian-squeeze Mailman is an open-source mailing list manager, i.e., it can be used to manage email discussions and newsletter lists. It is probably the most popular and widely used mailing list manager on the Internet. This tutorial explains how to install and configure Mailman on a Debian Squeeze server with a Postfix mail server. falko Tue, 19 Jul 2011 11:16:37 GMT http://www.howtoforge.com/installing-maia-mailguard-on-debian-lenny This guide explains how to install Maia Mailguard, a spam and virus management system, on a Debian Lenny mailserver. Maia Mailguard is a web-based interface and management system based on the popular amavisd-new email scanner and SpamAssassin. Written in Perl and PHP, Maia Mailguard gives end-users control over how their mail is processed by virus scanners and spam filters, while giving mail administrators the power to configure site-wide defaults and limits. falko Thu, 08 Jul 2010 11:02:10 GMT http://www.howtoforge.com/mailgraph_pflogsumm_debian_etch This article describes how you can monitor your Postfix mailserver with the tools Mailgraph and pflogsumm. Mailgraph creates daily, weekly, monthly, and yearly graphs of sent, received, bounced, and rejected emails and also of spam and viruses, if SpamAssassin and ClamAV are integrated into Postfix (e.g. using amavisd-new). These graphs can be accessed with a browser, whereas pflogsumm (Postfix Log Entry Summarizer) can be used to send reports of Postfix activity per email. falko Thu, 28 Jun 2007 10:18:54 GMT http://www.howtoforge.com/postfix-monitoring-with-mailgraph-and-pflogsumm-on-debian-lenny This article describes how you can monitor your Postfix mailserver with the tools Mailgraph and pflogsumm.

Virtual hosting means that you can add as many maildomains as you want and subsequentially as many mailboxes for these domains as you want. Here we we use an LDAP backend for both the MTA (Postfix) and POP3/IMAP server (Dovecot), and a web based management interface. falko Sun, 25 Jan 2009 12:39:08 GMT http://www.howtoforge.com/postfix-virtual-hosting-with-ldap-and-dovecot-on-ubuntu8.04 I have been running with a MySQL backend for virtual hosting for some time, but when I discovered Phamm and the added FTP feature I decided to switch to LDAP as backend for Postfix with virtual hosting. In view of the fact that the installation and configuration guide of Phamm is lacking some basic information it took me quite some time to put it all together and get it working. Piecing it all together was not simple so I would like to share how I configured it and got it all working toghether. falko Sun, 03 Aug 2008 11:05:20 GMT http://www.howtoforge.com/securing-your-ispconfig-3-installation-with-a-free-class1-ssl-certificate-from-startssl This tutorial shows how you can use a free Class1 SSL Certificate from StartSSL to secure your ISPConfig 3 installation and get rid of self-signed certificate warnings. The guide covers using the SSL certificate for the ISPConfig web interface (both Apache2 and nginx), Postfix (for TLS connections), Courier and Dovecot (for POP3s and IMAPs), and PureFTPd (for TLS/FTPES connections). If you've installed monit and use HTTPS for its web interface, I will show you how to use the StartSSL certificate for it as well. This guide assumes you use Debian or Ubuntu; the principle is the same for other distributions supported by ISPConfig 3, but paths might differ. falko Thu, 19 Jan 2012 11:10:32 GMT http://www.howtoforge.com/postfix_backup_mx In this tutorial I will show how you can set up a Postfix mailserver as a backup mail exchanger for a domain so that it accepts mails for this domain in case the primary mail exchanger is down or unreachable, and passes the mails on to the primary MX once that one is up again. falko Sun, 24 Jun 2007 12:24:20 GMT http://www.howtoforge.com/perfect_server_centos4.5 This tutorial shows how to set up a CentOS 4.5 server that offers all services needed by ISPs and web hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the 32-bit version of CentOS 4.5, but should apply to the 64-bit version with very little modifications as well. falko Mon, 04 Jun 2007 11:45:49 GMT
