Just found out that Mail.app was signing my emails with the wrong certificate as I have multiple certificates for my email address. Luckily it's easy to solve the problem with OSX 10.9 and Keychain Access. When selecting your preferred certificate, open the context menu and select "New Identity Preferenceā€¦". The following dialog enables you to provide an email address and the preferred certificate for it (with the currently selected certificate already filled in as default).
