I have email accounts of rediffmail, hotmail, MyRealBox (NoveL). I would like to use Thunderbird as my Email client to receive mails from all accounts.

I believe that's possible.
If you can use outlook then you can use TB instead.

Hotmail will be a pain as it's block e-mail client access unless you pay a fee.

Yahoo and hotmail have this thing that you have to pay to enable your email client to receive your mail because I think it has to do with their revenue because you won't be visiting their site anymore and you won't be clicking links that make them money
