application by KDE developer Zack Rusin, and Kontact was modified to support an array of mainly web based suites of collaboration software. Components Kontact embeds the following Summary Page: A summary which shows unread emails, upcoming appointments, and the latest news and weather from the user's subscribed RSS feeds Email KMail supports folders, filtering, viewing HTML mail, and international character sets. It can handle IMAP, IMAP IDLE, dIMAP, POP3, and local mailboxes for incoming mail. It can send mail via SMTP or sendmail protocols. It can forward HTML mail as an attachment but it cannot forward mail inline. Spam and filtering KMail uses two special filters to provide a modular access to spam-filtering programs: Send this e-mail 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 e-mail as its standard input. Pipe this e-mail through a program not only sends the e-mail to a specified program, but replaces the e-mail 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 e-mail. These modular filters can be combined with text filters to detect (for example) e-mail which has been flagged by SpamAssassin by looking for the special headers it added. KMail allows manual filtering of spam directly on the mail server, a very interesting feature for dial-up users. Emails that exceed some threshold size (standard is 50 kb, but it may be set to any value) are not automatically copied to the local computer. With "get, decide later, delete" options, KMail lists them but does not download the whole message, which allows the deletion of spam and oversized messages without wasting time. Cryptographic support KMail supports the OpenPGP standard and can automatically encrypt, decrypt, sign, and verify signatures of email messages and its attachments via either the inline or OpenPGP/MIME method of signing/encryption. KMail depends on the GnuPG software for this functionality. As a visual aid, KMail will colour verified email messages green for trusted signatures; yellow for untrusted signatures; red for invalid signatures; and blue for encrypted messages. KMail also supports S/MIME messages as well as Chiasmus, a proprietary cryptographic system created by the German Federal Office for Information Security (BSI).
