I actually support Evolution and Thunderbird. Each has its virtues and downfalls. Evolution's integration with Exchange systems saves me from the horrors of OWA, while Thunderbird's extensibility makes it extremely flexible.
So, what does the Texas Board of Education use as a back-end for their mail system?
Wait, what was the summary again??? And why is Evolution capitalized in the article's title???
