I would use it but I worry about using programs that are not being actively maintained because of the risk of security vulnerabilities. Especially in email where you can have a lot of risky inputs (spam, phishing attempts etc) - even though I have great spam protection (thanks pobox) there is still a risk. I'm not sure what I'm going to do on Windows yet... I'm trying Postbox and it's nice.
