SUMMARY Since 5.20 or maybe even before, kmail is sending read receipts despite setting it not to do so (both with "ignore" and with "ask each time" an clicking "ignore"). Not sure if this comes down to Gmail, as it's the backend for the email accounts I have to use, but the very second I open an email with a read receipt, kmail sends it. STEPS TO REPRODUCE 1. Set kmail to ignore read receipts (Settings->Security->Message Disposition Notifications->Send Policy->Ignore (or ask) 2. Open an email with a read receipt (and click "ignore" if you set "ask" in the previous step) OBSERVED RESULT Kmail will send the read receipt immediately, no matter what setting you have in the first step. EXPECTED RESULT Kmail will never send any read receipt if you set "Ignore" (or "Ask" and you click "ignore" in an email with a read receipt). SOFTWARE/OS VERSIONS Linux: Kernel 5.18.0 KDE Plasma Version: Plasma 5.25.1 KDE Frameworks Version: 5.95.0 Qt Version: 5.15.4
Here it works fine. Ignore will not send. Ask -> ignore will not send.
