Build a Secure Webmail Service Supporting IMAP and SSL
The combination of software we are using is Apache with mod_ssl and PHP4, and the webmail package we describe below is Aeromail. We chose this combination because it is under active development (as of this writing), easy to install and quite feature rich. We also describe some additional webmail packages at the end of the article and provide several resources for more information.
We assume you haven't installed a web server or the SSL libraries on your system, which we will cover here. While it may seem like a lot of different components, it's really quite simple. Furthermore, your secure web server can be used for other things you may wish to try.
