If you in-charge of IT infrastructure in your enterprise, imagine walking into your office, logging into the company ticketing system and finding zero tickets! But you're not surprised. After all the secure multi-site, scalable, mail transfer agent Postfix you've deployed is delivering corporate email to everyone using encrypted protocols, even to employees on the move. The system flushes all spam messages before delivering them to their new offline mail client or their AJAX-based web mailboxes. In fact, what you do get are a couple of "Thank You" notes from people who are in love with the voicemail solution that you've integrated with the email system to allow them to read emails via a telephone!
Sounds too good be true? But it really isn't! Not only is it all very possible, you can put together such a system without spending a single dollar. It's all about Open Source honey :)
Allow me to briefly plug the o3 Magazine here that I am involved with as Editor-in-Chief. Note: I am no longer associated with o3 magazine. But I rather not. All I'll do is point you to our current issue, Issue 8, which helps you put together the enterprise-grade email system that I just described above and my task is done :)
This issue looks at how to build secure SMTP appliances with Postfix, moves on to using Dovecot to provide IMAP and POP3 and then looks at RoundCube to provide a web-mail solution, followed up with an article on deploying DSPAM with ClamAV for anti-spam / anti-virus protection. The issue then looks at Encrypting email protocols, integrating Voicemail with Email systems, and finally at MobilityEmail as a replacement for Outlook on Windows clients. Also don't miss the Voicemail / Email integration with Asterisk article, and we pushed the envelope a little to do voicemail to text translation with Julius, a real-time speech recognition project.
