User-Agent: Mozilla/5.0 (X11; Linux x86_64) KHTML/4.8.2 (like Gecko) Konqueror/4.8 Build Identifier: Kmail hides the sender email, when a sender name is available. Problem: The sender name is nothing real and can be changed vert easily by the sender. possible solution 1: add a column which contains the email-address of the sender. possible solution 2: hide the email-address only, when an exact match is found in the addressbook. Thanks Reproducible: Always
