Thunderbird is a desktop app which runs on machines with 1TB disk, quad 4G cpu, 20 GB ram, and disks able to feed 300MB/s. It has the ressources to perform very complex rules and neural network. Mobile phones won't have these ressources before years. And TB is not doing good job (basic features are still stated as feature requests since over 13 years in bugzilla ).
