To make self-service easier and be less restricted by limits when sending out larger amounts of emails, we migrated to our own E-Mail server.
If you happen to own an @nixos.org address, you can test now if you email alias still works as expected.
As the email server is quite new we expect that some email server might put our forwarded emails into spam for a some time, so please check also the spam folder and move it out of spam to train the spam filter.
