Hi there, just upgraded to kmail 6.3.3 A search for an email address inside kmail2 (used via kontact) doesn't work anymore as usual. For example I received a mail from a sender formated in mail like .... From: Hillbilly Jones <hillbil0815@gmail.com> To: company4711@googlemail.com .. Search by sender (from: ) "hillbil0815@gmail.com" doesn't get any result, search by "hillbil" get results. At the same time a search for "hillbil0815@gmail.com" in roundcube functions. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Archlinux (Wayland) KDE Plasma Version: 6.3.3 KMail KDE Frameworks Version: 6.11.0 Qt Version: 6.8.2 I'm sorry for my english, if you need additional information I'll provide additional informations
