Also, don't open HTML mail but use the plaintext alternative where available. If you can't avoid HTML mail, many mail services have some tracking protection built-in. poc

They might have turned receipts off. 2. Getting a read receipt cannot be interpreted as meaning that the receiver did read the message (let alone understood it). To sum up: read receipts are a misfeature, except in the special case of internal mail where they are part of corporate policy. poc

I'm reminded of a scene in a tv comedy series about government bureaucracy, where in one episode their email server was down, but they were still emailing each other by passing their laptops around.

I finally remembered to do the right thing, and checked the claws-mail online man pages. It does support both sending and receiving return receipts. Here is the snippet from their FAQ about this: """ 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. You can choose to never send Return Receipts by using the option on the Mail Handling/Sending page of the Preferences. When you use this option, all Return Receipt requests are ignored and you will not be prompted to send one. """ And I have that turned off, so at some point in the past I must have been concerned about it, turned it off, and forgot completely ever being concerned. Sigh.
