Version: 1.13.2 (using 4.4.2 (KDE 4.4.2), Kubuntu packages) Compiler: cc OS: Linux (x86_64) release 2.6.32-21-generic This is a feature many MUAs have: An extra address book to which addresses from people I send mails to or reply to are automatically added. I think its called "Collected Addresses" in most cases.
To clarify: KMail2 does collect my addresses, what I'd like to have is a "real" addressbook stored in Akonadi instead of the current kconfig store.
