I'm sending a small quantity of email through gmail. Would I be more exposed if i setup my gmail accounts to work through Thunderbird? Would it pass on my ip information?

Have to use proxies to hide your ip

use tor and setup thbird to work thrugh it.

it will take longer but it wont be you ip

I would not advise you use either. First of all the tor + thunderbird scenario is not plausible because your mail would never go out and regular old proxies wont do the trick either. What do you consider a "small quantity"?
