HW: How long have you been using Mail.app? What other clients have you used (and why did you stop)?
BS: I currently use Entourage mostly, because it works much better than Mail.app with our Exchange system.
I’ve used Mail.app in the past, though — along with Eudora, Mailsmith, pine, and mutt.
Actually, I do use Mail.app exclusively with my .Mac email address. And of course I use it as a developer (figuring out how to make it so you can send email from NetNewsWire via Mail.app).
HW: What plugins and extensions do you use to make your email experience better?
