Version: (using KDE KDE 3.5.8) Installed from: SuSE RPMs I believe it is a regression (if not please switch it to wish). Anyway, let's say you have mail from "joe.doe@gmail.com". No problem searching for "joe.doe" (via quick search). But if the sender uses such identity (from field): Joe Doe <joe.doe@gmail.com> you cannot search for "joe.doe" any longer because KMail sees only "Joe Doe" part as a sender.
I believe this is bug 99094. The from column does not display the e-mail address, so it is not searched. *** This bug has been marked as a duplicate of 99094 ***
Thomas, you are right, thank you.
