I have 3 GMail, 2 Yahoo! Mail and 1 Hotmail account and I want to manage all of them from one place. I recently started using Mozilla Thunderbird, but I have some problems with it.
First is that I have problems in adding few email accounts. One of my Yahoo! Mail accounts is receiving messages while other one always gives password error, although the password is correct. Also, I want to know about POP and IMAP because I don’t know anything about these.
