KMail - Definition and Overview

KMail using the default layout: the folder list on the left side and the preview pane below the message list (top right)

KMail is the email client in KDE. It supports folders, filtering, viewing HTML mail, and international character sets. It can send mail to any program or to an arbitrary port (normally 25) of a mail server.

Spam and filtering

KMail uses two special filters to provide a modular access to spam-filtering programs:

• Send this email to a program allows any program to be specified, and when that KMail filter is activated, the program will be run and supplied with the contents of the email as its standard input.
• Pipe this email through a program not only sends the email to a specified program, but replaces the email with the output of that program. This allows the use of systems such as SpamAssassin which can add their own headers to a piece of email.

These modular filters can be combined with text filters to detect (for example) email which has been flagged by SpamAssassin by looking for the special headers it added.

Cryptographic support

KMail has built-in support for OpenPGP email, and will automatically decrypt messages and check the signature once the user has typed their password, displaying such messages with a blue or green border to show that they were encrypted.

Groupware support

When used as part of the Kontact Personal information manager suite, KMail can act as a groupware client, sharing contact lists, email, calendars, and notes between users.
