Version: (using KDE KDE 3.1.2) Installed from: Compiled From Sources I wish that if you receive an email with a header such as From: Real name <user@domain> Reply-To: user@domain that KMail would reply to "Real name <user@domain>" (identical address) or add the real name to Reply-To: address if the Reply-To: address is contained in your addressbook.
In KDE 4.3 kmail does what you want.
