== How MUAs reply to email messages ==
MUAs have (at least) two reply functions: reply-to-author and reply-to-all. In Thunderbird they are just called "Reply" and "Reply all".
If you reply-to-author, your MUA creates a new message and sets the To header to the original message's From header. If the original message contains a Reply-To header, your MUA uses its content instead of From. This way the original message's author can tell you to reply to another address if he wants to get replies there.
If you reply-to-all, your MUA creates a new message and sets the To header like above. Additionally it sets the new messages message's Cc header to the list of all recipients (To+Cc) of the original message, probably excluding your own address.
