Hey all, it seems that with return receipts messages there is no x-sender header. Is that on purpose?

i guess "return receipts" means NDA / bounces

• roundcube is just a client and don't mangle messages
• any header starting with X- is *non-standard* at all

That's all fine, but normal emails produced through compose do have an x-sender.

And actually, I looked wrong. Return receipts do get an x-sender, but these emails are probably not going through message_outgoing_headers hook. I have a plugin that adds encrypted real user to outgoing headers, and I noticed return receipts weren't getting them.

So to rephrase, am I right in concluding that return receipts dont pass message_outgoing_headers ? Is that fixable?

Confirmed. 'message_outgoing_headers' is only called for composed messages. But in the source I see the following:

// exec hook for header checking and manipulation // Depracated: use message_before_send hook instead $data = $RCMAIL->plugins->exec_hook('message_outgoing_headers', array('headers' => $headers));

Thus you should use the 'message_before_send' hook which is triggered for all outgoing messages including return receipts.

Great! Thanks for the info,
