Gmail bounce unauthenticated @debian.org addresses
We recently discovered that Gmail started to bounce email from
mentors.debian.net with the following message:
550-5.7.26 This message does not have authentication information or
fails to 550-5.7.26 pass authentication
checks. To best protect our users from spam, the 550-5.7.26 message has
been blocked. Please visit 550-5.7.26
https://support.google.com/mail/answer/81126#authentication for more 5
50 5.7.26 information.
My debian address is also affected, and probably others that did not
setup DKIM for their @debian.org address.
As a reminder debian.org addresses does support DKIM. After
configuration on your mail server, you can publish your DKIM public key
to db.debian.org .
