MailMate 1.9.7 brings a long list of improvements and fixes as documented in the detailed release notes. Here follows a short list of the most notable highlights:

  • Improved single message window behavior. It is now “connected” to the main window such that undo/redo behavior is better and features (key bindings) such as “Move to Mailbox…” work as expected.
  • The “Apply Rules” menu item is now a menu which allows applying rules to either selected messages or the entire mailbox.
  • “Export ▸ Copy to Folder” command which exports .eml files into a folder hierarchy matching the original accounts. Duplicates are automatically avoided and the command can be used as an action in mailbox rules.
  • Internal changes to provide an action for bundles which allows changing header values of existing emails. This feature is currently used to implement “Command ▸ MailMate ▸ Change Subject”.
  • Email addresses can now be blacklisted such that they are not used for completions in the Composer.
  • Low-level, the message list supports coloring and styling lines. This feature is described in more detail here.
  • Numerous new hidden preferences for users that like to tinker with the details.
  • Manual pages updated to include some of the previously undocumented features.
  • Improved behavior for various problematic IMAP servers including Gmail and Exchange IMAP.
  • Uses the IMAP RENAME command when an IMAP mailbox is renamed (also when a hierarchy is involved). This is both more robust and more efficient than before.
  • Now doing Gmail “OAuth2” authorization through an external browser.
  • Improved composer text view including fixing various display issues.
  • Improved autoscroll in the composer preview
  • Improved and fixed S/MIME handling which now also allows separate certificates for signing/encrypting.
  • Improved behavior for window tabs on Sierra and later macOS versions.
  • Fixed various issues on High Sierra.
