Aside the specific issue, i found adding this option was the only way to make my little MUA work with OpenSMTPD 6.0.2p1, as that joined the command line arguments onto all receivers given in the message itself, resulting in duplicate deliveries. While this possibly was a bug, i added *mta-no-receiver-arguments* in October 2017 to address this issue. |Thanks for any advice or input!
