Thunderbird
In the age of Twitter, SMS and IM is e-mail obsolete? Not yet. Like it or not, most of us gets dozens, even hundreds, of e-mails a day. Since that's the case, why not look for the easiest and least costly way to manage that flood of useful--and useless-- information?
I feel as though I have been waiting for Thunderbird 3 for ever - but now it is finally out there. This article in Network World discusses some of the new Thunderbird direction and features.
I have installed on top the default Kubuntu Thunderbird 2 (after backing up the .mozilla-thunderbird directory) a couple of days ago, and, apart from a couple of small problems, it has worked well.
I have over fifteen years experience in systems and network configuration and support. For most of that time I have been working with Open Source Software, and believe that Open Source software provides the best solutions for business, educational and personal use.
