Claws Mail

Claws Mail

Claws Mail is an email client aiming at being fast, easy-to-use and powerful. It is mostly desktop-independent, but tries to integrate with your desktop as best as possible. The Claws Mail developers try hard to keep it lightweight, so that it should be usable on low-end computers without much memory or CPU power.

Claws Mail sports almost everything a perfect email client needs. Mail retrieval over POP3, IMAP4, local mbox, over SSL; support for various authentication schemes. It has multiple accounts and mailboxes, powerful filtering and search functionality, import/export capabilities using a number of formats, support for GnuPG (digital signatures and encryption). It supports plugins, customisable toolbars, spell checking, a number of guards to prevent any data loss, per-folder preferences, and much more. A list of features can be found here.

Formerly known as Sylpheed-Claws, it started in April 2001 as the development version of Sylpheed, where new features could be tested and debugged, but evolved enough to now be a completely separate program. It forked completely from Sylpheed in August 2005.

What's new in Claws Mail

  • Text zooming in the Message View is now possible, using CTRL+mouse wheel up/down, CRTL+touchpad two-fingered vertical swiping, or the Message View's right-click menu.
  • GtkColorChooser is now used in the Spell Checking preferences, Colour Label preferences, and the folder Properties pages.
  • 'Default From:' has been added to the Compose page of the folder Properties. This allows setting an email address which will override the Account's email address.
  • An option has been added to the 'General' page of the folder Properties, 'Skip folder when searching for unread or new messages', so that the folder can be skipped when using Go To next/previous unread/new message.
  • 'By Sender' has been added to '/Tools/Create filtering rule/...' and '/Tools/Create processing rule/...'
  • The option 'Run processing rules before marking all messages in a folder as read or unread' has been added to '/Configuration/Preferences/Display/Summaries'.
  • It is now possible to add a toolbar button to 'Run folder processing rules'.
  • The Actions configuration list now has 'Top' and 'Bottom' buttons.
  • In '/Tools/List URLs' it is now possible to CTRL+c or right-click a list item and 'Copy URL'; copying multiple selections is also possible. Phishing URLs are now indicated in red by default. This uses the colour defined in the hidden preference, log_error_color.
  • The method of handling Tags has been improved.
  • When using the separate Message View the Enter key will open the currently selected message in the Message List. So, for example, if you delete the current message, pressing Enter will open the next message without having to leave the separate Message View.
  • The quicksearch type-ahead keypress delay is now customizable using a hidden preference ("qs_press_timeout").
  • Improvements to the storage of OAuth2 refresh tokens.
  • A "View all" button has been added to the Themes preferences page in order to preview all icons of a theme.
  • The term 'master passphrase' has been replaced in the UI with 'primary passphrase'.
  • The label 'SSL/TLS' has been replaced with 'TLS' in the UI.
  • chmod 0600 is set on log files, history files, saved parts, etc.
  • "Keyword Warner" plugin has been added. This shows a warning when sending or queueing a message and a reference to one or more user-defined keywords are found in the message text.
  • Adding a new RSSyl feed or subscribing to a Webcal will automatically suggest using any suitable URI found on the clipboard.
  • The user manuals have been updated.
  • Updated translations: Brazilian Portuguese, British English, Catalan, Czech, French, Indonesian, Polish, Romanian, Russian, Slovak, Spanish, Turkish. [full release notes]
