Hi macports devs, as you know, our setup to send emails from aliases under the MacPorts domain currently is to use your own mail servers to do so using aliasing rules.
It is becoming increasingly obvious that this will no longer work, since many services are now treating our intentionally lenient SPF record and a few other behaviors of our mailserver (such as the lack of DKIM signing) as indicators that we are sending spam. As evidence of this, I can tell you that we're on the cloudmark IP blacklist for the second time in a couple of weeks. As a consequence, I will be setting up an SMTP submission service on our server. I will also provide a self-service to set your SMTP password that will leverage GitHub OAuth2 authentication. Once this is done, I'll send further detailed instructions on how to set your password and configure your mail clients to use that submission server. I will also lay out a timeline for you to change to the new mail sending setup. After the deadline has passed, we will change the SPF and DKIM records for macports.org, so mail sent from your current setup will be classified as spam, and likely even be rejected by our mailing list. Watch this space for further notifications! -- Clemens
