Description

KMail is the email client of the KDE project and part of the Kontact groupware suite. It offers extensive email management with support for multiple accounts, IMAP, POP3, filter rules, and GPG/S-MIME encryption. KMail integrates seamlessly with KOrganizer (calendar), KAddressBook (contacts), and Akregator (RSS). It provides powerful anti-spam features and supports large mailboxes with high performance thanks to the Akonadi database.
