• XP Look
  All toolbars and buttons now look more like Windows XP applications. All icons are true color (including the tray icon). The PopTray controls now also support XP themes.
• Plug-ins
  PopTray 3.x now supports plug-ins. These are DLLs copied into your plugins directory for more functionality in PopTray. PopTray 3.0 supports two types of plugins: Protocol and Notify. Example plugins (like IMAP4, POP3SSL, Hotmail) are available for download from the PopTray website.
• Attachments
  The preview screen now has proper support for attachments. It will list them with icons, and you can save them to disk.
• White List / Black List
  Quickly list your friends and enemy e-mail address. Messages from anyone in the black list will be deleted (or marked as spam) without you having to create a rule. Mail from people in the white list will be protected against auto-deletion.
• Customizable Toolbars
  There are three fully customizable toolbars (mail,accounts,rules). Use drag-and-drop to add and remove buttons from the toolbar.
• Options new look
  The options screen has been redesigned with a tree-view to break the options into logical divisions.
• New Options
  The following new options have been added:
  • Remember viewed Messages - Poptray will remember when you've viewed a message and save the IDs to disk so it will be saved even after quiting the program.
  • Quick Checking - Quick Checking has been improved a lot. With this option only new message headers will be downloaded.
  • Advanced Show Info - This will pop-up a info window showing all new messages since your last check. Also show a summary of all your accounts, and includes buttons to quickly run your e-mail client or ignore the new mail.
  • Hide Viewed Messages - This is handy for people the leave their messages on the server and don't want the PopTray window cluttered with old messages.
  • Don't Check between - Specify the hours that you want to automatically disable checking in PopTray.
  • Retrieve Body while Checking - Usefull when you have fast connection. The complete body can be checked by the rules, and also external Bayesian filters can analize your message body.
• Command-line Options
  PopTray now supports calling actions from the command-line for powerful scheduling options.
