KMail is the KDE mail application. In addition to sending and receiving e-mail and using multiple mail protocols, it offers the possibility to configure several user-defined filters for sorting e-mail messages in individual folders. The encryption, decryption, and signing of e-mail messages can also be handled conveniently in KMail.
KMail can save messages in the following formats:
This traditional UNIX format (the oldest) saves all messages in a single file. Directories are also simulated by means of individual files. The individual mails can only be distinguished by the From line.
In contrast to the mbox format, the MailDir format has a unique file name for every message. The messages are stored in the respective directories and can easily be identified and further processed. KMail uses the MailDir format (as the more convenient alternative) by default, but MailDir is not supported by many other e-mail programs. This can be a disadvantage if you want to switch to a different e-mail programm later and still access your old e-mails. Processing old mails in mbox format is no problem, however, if you select MailDir. Just copy or move the files to the MailDir folder.
