The Thunderbird has landed
Yes, I know, I'm two days late...
But I just have to mention it again, that Mozilla Thunderbird 1.0 has been released two days ago.
The most important built-in feature for me is the automatic spam filter which keeps my inbox spam-free ~99 percent of the time. I'm getting about a dozend spam mails a day and only about once a week one of them slips into my inbox. So far I've never had a false positive.
Another Mozilla product I'm keeping my eyes on is Mozilla Sunbird(Calendar) which is I think the last missing piece to complete my office experience. Sadly it still lacks propper MS Exchange integration which disqualifies it for my work environment but I expect that to appear somewhere in the future, because it's on third place when I query bugzilla.mozilla.org for the most-voted-bugs on Calendar.
