Talking SOAP With Exchange

Mon, 08 Dec 2008 17:29:37 +0100

Talking SOAP With Exchange

Previously, talking to Exchange without using Microsoft products was pretty much out of the question. The binary MAPI protocol is proprietary and poorly documented. Exchange supports IMAP and POP, but these protocols only give acesss to emails, not the calendar, address book, todo lists etc. But beginning with version 2007, Exchange now ships with a SOAP interface called Exchange Web Services, or EWS. This interface gives us access to the functions necessary to write clients in any programming language on any platform. This article describes a PHP program to look up, delete and insert items in an Exchange calendar.

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 8.10)

Thu, 13 Nov 2008 18:59:54 +0100

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 8.10)

This document describes how to install a mail server based on Postfix 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. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

Automatic Cleaning Of Trash And/Or Junk Folders With ISPConfig (With Roundcube + Tmpreaper (Tmpwatch))

This short mini-howto will help you set up automatic cleaning of Trash- and Junkfolders. Most (web)mail clients (can) automatically create these. A lot of people don't clean there maildirectories causing Junk and Trash folders to grow massively in size and with ISPConfig (not yet) being able to set good maildirectory size limits the alternative is to have these folders cleaned after several days.

Postfix Virtual Hosting With LDAP Backend With Dovecot As IMAP/POP3 Server On Ubuntu Hardy Heron 8.04 TLS

Wed, 30 Jul 2008 18:17:49 +0200

Postfix Virtual Hosting With LDAP Backend With Dovecot As IMAP/POP3 Server On Ubuntu Hardy Heron 8.04 TLS

I've been running with a MySQL backend for virtual hosting for some time, but when I discovered Phamm and the added FTP feature (amongst others) 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 (including crying, swearing, getting depressed, ...) to put it all together and get it working. Long live google to find hints or explanations for problems and configuration issues. Piecing it all together wasn't simple so I would like to share how I configured it and got it all working toghether (as I like), but I think that it will benefit other users as well.

Exim Authenticated Smarthost

Exim Authenticated Smarthost

Today's ISP environment requires authenticated SMTP to be able to send emails. As a policy, authenticated SMTP helps cut down on folks sending SPAM and allows the ISP to track which account is sending what type of email content for further demographic study. While authenticated SMTP is good for the ISP, it is not a configuration supported out of the box by most Linux distributions. This means that all those system emails and log reports emailed by root never make it anywhere anymore.
