Hi folks, my MTA (opensmtpd on OpenBSD 7.0) rejects a few EMails with a message like
May 27 08:42:30 mymta smtpd[10310]: f06a752b657b4a05 smtp failed-command command="RCPT TO:<[email protected]> ORCPT=rfc822;[email protected]" result="550 Invalid recipient: <[email protected]>" in /var/log/maillog. The EMails to [email protected] without "ORCPT=rfc822;" are accepted and forwarded as usual. All EMails with "ORCPT=rfc822;" to any user are rejected. I have found https://github.com/OpenSMTPD/OpenSMTPD/issues/658 of course, but I don't see a configuration issue on my side. My MTA is just an MTA, there are no local users except for root. Every insightful comment is highly appreciated Harri
