I, too have tried evolution several times. I'm still using Thunderbird. Will the new version do calendaring with Outlook users? We don't use an exchange server, but our customers have standardized on Outlook calender, and we need to be able to request meetings, etc. I would like to be able to work with google calendar. Is there a plugin, and/or working synch app to keep a calendar synched to google? * Spam filtering. at first they expected us to manage a SpamAssassin install. That is NOT a reasonable solution for most users. What spam filtering plug-ins do they have now? Finally : secure e-mail. Are there plug-ins for PGP/GPG? S/MIME? We use S/MIME at work, but I still use my old GPG key for personal communications. »

Excellent introductory article. I will be keeping this in mind while designing a new application. I always wondered if there was a way to control aspects of NUMA. I now have a starting point for researching these NUMA control techniques. »
