Talking SOAP With Exchange

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)

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.
