I would like to know how good I Mozilla Thunderbird. Is it as good as the hype suggests? Does it offer much more than the regular Outlook Express/Outlook, etc and does it have more features for Spam Blockage? One more thing, is it possible to view Emails of my Gmail ID using any Mail client like Outlook Express, Thunderbird, etc. If so, can you tell me how? Do all other mailers support this?
