Does Claws Mail support Return Receipts? Yes. To request a Return Receipt use Options/Request Return Receipt in the Compose window. When you receive a message that requests a Return Receipt a notification area is shown just above the message view. You can either use the Send receipt button, or ignore the request - no receipts are sent automatically. If you do not ever want to send Return Receipts then you can use the option Never send Return Receipts in the Configuration/Preferences/Mail Handling/Sending page.
How can I make Claws Mail notify me when new mail arrives? Go to Configuration/Preferences, in the Mail Handling/Receiving section, use the settings for Run command in the After receiving new mail frame. Alternatively, use the Trayicon plugin.
Why are special characters (e.g. umlauts) not displayed correctly? In most cases, this is caused by emails with broken encodings. You can try to force it using the View/Character Encoding submenu.
Can I quote just a section of the original message when replying? Yes, select the section of the message that you want to quote and use Reply.
