Re: Received e-mails in Spams (bad e-mail server configuration / ML configuration)
Hello,
I also join this, I have to set up whitelists to receive the emails.
On phpMyAdmin I tried to set the Sender header but it does not work that well.
mailman has "DMARC mitigations" that are quite effective by replacing the From by a name hosted on the sending domain.
At least do like email hosting platforms and provide a _spf.debian.org so users can use "include:_spf.debian.org" without guessing the full list of Debian servers that send emails.
