It is known for its extensibility (thanks to plugins), low resource consumption, and customizable flexibility. The project is aimed at experienced users but remains accessible to anyone who values efficiency and minimalism.<\/p>\n<p>On March 9, 2026, version <strong>4.4.0<\/strong>, which is noteworthy not only for its technical improvements but also for the symbolic date \u2014 the project turns <strong>25 years old<\/strong>.<\/p>\n<h2>Change log:<\/h2>\n<h3>User Interface<\/h3>\n<ul>\n<li>Text strings and icons have been updated.<\/li>\n<li>The term 'Compose' has been replaced with 'Write'. For example: 'Write a letter', settings page 'Writing', etc.<\/li>\n<li>By default, the horizontal scrollbar in the email list is hidden unless the GENERIC_UMPC mode is used.<\/li>\n<li>A hidden setting mainwin_toolbar_always_enable_actions has been added (disabled by default). When enabled, buttons on the toolbar related to user actions remain active even if no email is selected.<\/li>\n<li>Navigation using the arrow keys on the numeric keypad (numpad) has been implemented.<\/li>\n<li>A new item has been added to the color settings: 'Emails marked for moving or deletion'. This is used when the 'execute immediately' mode is disabled.<\/li>\n<li>Compose window: When re-editing a draft, the program now prompts for confirmation to save changes made to the headers.<\/li>\n<li>Compose window: When clearing the content of the subject field, the 'Clear' button turns into a 'Remove' button, allowing you to completely remove the now-empty line.<\/li>\n<li>Folder Properties: Two new options for working with HTML have been added to the 'General' tab: 'Display HTML emails as text' and 'Display HTML emails using a plugin, if possible'.<\/li>\n<li>Folder Properties: A new option 'Show tags' has been added to control the display of message tags at the top of the email viewing area.<\/li>\n<\/ul>\n<h3>Plugins<\/h3>\n<ul>\n<li><strong>SpamAssassin:<\/strong> Third-party code has been updated to version 4.0.1.<\/li>\n<li><strong>Mail Archiver:<\/strong> Support for Zstandard (zstd) compression has been added (requires libarchive &gt;= 3.4.0).<\/li>\n<li><strong>RSSyl:<\/strong> The default User-Agent string has been changed to ClawsMailRSSyl\/$VERSION ($URL). It can be changed in the plugin settings and individually set for each feed on its properties page.<\/li>\n<li><strong>RSSyl:<\/strong> A setting has been added that prevents feeds configured for manual updates from updating when all feeds are refreshed (recursively through the context menu, by timer, or at startup if enabled).<\/li>\n<li><strong>RSSyl:<\/strong> Implemented saving and sending ETag and Last-Modified headers.<\/li>\n<li><strong>RSSyl:<\/strong> Auto-updates are delayed if <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/en\/server\/\"   title=\"server\" data-wpil-keyword-link=\"linked\">server<\/a> the Retry-After header is sent. A successful manual update resets this value.<\/li>\n<li><strong>PGP:<\/strong> In the NoticeView area, the message 'This key is not in your keyring' is displayed if the key is missing.<\/li>\n<li><strong>PGP:<\/strong> An option has been added to automatically search for missing keys when sending encrypted messages.<\/li>\n<li><strong>PGP:<\/strong> A missing key can now be obtained by clicking on the icon in the NoticeView area.<\/li>\n<li><strong>PGP:<\/strong> A 'Find PGP Key' option has been added to the context menu for email addresses in the message viewer.<\/li>\n<li><strong>Notification:<\/strong> For the Ayatana indicator, the ability to limit notifications to specific folders has been added.<\/li>\n<li><strong>Notification:<\/strong> A 'Open Address Book' option has been added to the Ayatana indicator menu.<\/li>\n<\/ul>\n<h3>OAUTH2<\/h3>\n<ul>\n<li>Configuration is now stored in a separate oauth2rc file located in the settings directory. This file allows the user to adapt to API changes from the provider or to add a completely new OAuth2 provider of their choice. Setting the protected=1 parameter inside an edited or newly created block protects it from being overwritten during Claws Mail updates.<\/li>\n<\/ul>\n<h3>Build system<\/h3>\n<ul>\n<li>The minimum required version of GnuTLS has been raised to 3.4.0.<\/li>\n<li>The minimum required version of libetpan has been raised to 1.9.4.<\/li>\n<li>Support for dbus-glib has been migrated to GDBus (GIO) version 2.26 or higher and D-Bus (0.60 or higher).<\/li>\n<li>Output summary of configure has been supplemented.<\/li>\n<\/ul>\n<h3>Other<\/h3>\n<ul>\n<li>A hidden setting show_contact_pic has been added. When viewing a message, if the sender is in the address book and a picture is saved for them, this option will allow that image to be displayed (if the header panel is not shown, display (X-)Face is not disabled, and enable_avatars is not set to 0). It is recommended to disable this option if there is a large address book to avoid delays in message display.<\/li>\n<li>The setup wizard now uses secure default settings.<\/li>\n<li>Various code cleanups, fixes, and improvements.<\/li>\n<li>User manuals have been updated in English, French, and Spanish.<\/li>\n<li>Updated translations: British English, Catalan, Czech, Dutch, French, German, Romanian, Slovak, Spanish, Swedish, Turkish.<\/li>\n<li>Error corrections:\n<ul>\n<li>bug 4498: issues with resizing the 'About' window.<\/li>\n<li>bug 4586: display issue in three-column mode when using the PDF Viewer plugin.<\/li>\n<li>bug 4764: displaying nonexistent quotes in the email subject with line breaks in UTF-8 encoding.<\/li>\n<li>bug 4834: long email addresses in vCalendar invitations hid the attachments panel until restart.<\/li>\n<li>bug 4841: quoted-printable encoding broke text\/html files with very long lines, unlike base64.<\/li>\n<li>bug 4846: in toolbar settings, always show icon preview on the button.<\/li>\n<li>bug 4848: new icon in the Ayatana tray did not display when new messages were present.<\/li>\n<li>bug 4850: displaying an error dialog when there is an error fetching mail (translation).<\/li>\n<li>bug 4852: canceled messages contained the header Approved.<\/li>\n<li>bug 4854: disabled line wrapping did not work when using an external editor.<\/li>\n<li>bug 4856: build error with gettext 0.24.<\/li>\n<li>bug 4863: minor interface inconsistency in account settings.<\/li>\n<li>bug 4882: IMAP could not use a client certificate with a passphrase.<\/li>\n<li>bug 4887: Dillo processes did not terminate when the HTML message was no longer viewed.<\/li>\n<li>bug 4893: Clamd plugin did not check mail.<\/li>\n<li>bug 4897: 'small screen' mode: crash when exiting the message list view after deleting all messages in the folder.<\/li>\n<li>bug 4898: when entering a folder, the message list did not scroll to the selected email.<\/li>\n<li>bug 4902: memory leak in spam_report plugin.<\/li>\n<li>bug 4930: duplicate signature flag removed from MimeView.<\/li>\n<li>bug 4931: memory leak fixed in summary_set_header.<\/li>\n<li>Fixed an issue that caused viewing emails in a separate window not to mark them as read when the preview pane was hidden.<\/li>\n<li>Fixed build error with the litehtml plugin on Windows.<\/li>\n<li>\"Save email as&hellip;\" from a separate view window saved what was selected in the email list, not what was opened in the view window.<\/li>\n<li>Fixed a sequence of actions leading to a crash when the view window was closed.<\/li>\n<li>Fixed a header panel issue where a very long header value pushed the MIME icon panel out of the visible area.<\/li>\n<li>No more attempts to remove the tag from the list occur when the input focus is on the tag editing field.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>Source: <a \ncontent=\"nofollow\" rel=\"nofollow\"
