In the past months, it's been clear that sending mails from an
@debian.org address to some mail providers, including GMail, has become
harder and harder. While user DKIM feature (documented on [0]) can help,
we thought providing a relay server for our users to send their Debian
mail was a more long-term solution.
This service is now operational behind mail-submit.debian.org (AKA
stravinsky.debian.org). Documentation about how to use this service can
be accessed via [1]. The page behind [0] will be updated on the next
release we make of userdir-ldap-cgi.
Mails sent via this server will be DKIM-signed if the from is a
debian.org, debconf.org or ftp-master.debian.org address. If any
additional domain should be considered, feel free to ask.
This server requires an active Debian Account, and that one sets their
mailPassword up (again, see [1]) to be able to use the service. I've
tried to provide some useful tips on the doc.
If you have any question or issue, please don't hesitate to reach out.
