Hi folks, https://www.opensmtpd.org/list.html doesn't tell how to unsubscribe an old EMail address, that cannot be used for sending EMails anymore. The same page doesn't list an administrative user, either, so please excuse sending this question to this mailing list.
I tried to send an EMail (new address) to misc+unsubscr...@opensmtpd.org saying unsubscribe o...@example.com but this didn't work as expected. The EMail address was ignored. Every helpful hint is highly appreciated. Harri
