Reply to the person you earlier sent an email to in Desktop mail clients

There are many things I like about a desktop email client instead of a Web based application e.g. More and better filters, easy backup etc. but I hate Outlook and Mail (have not tried this in Thunderbird) for one reason – If I hit Reply to a sent message in my Sent folder to an email I sent to email@example.com, the email address it puts in the To field is mine and not email@example.com.

Now, I do not know if there is a setting in these email clients that I am unaware of (I’d be glad if someone can point out). All I know is that its in the Gmail’s Web Interface, which is slick. It knows that you want to reply to the person you sent that last email to and not yourself.
