Hi,
since 8/1/2023 I get complains from users with @gmail.com addresses, that they are not getting any emails. I checked the logs and I see that the emails are going out:
to=<xxxx@gmail.com>, relay=email-smtp.us-east-1.amazonaws.com[35.169.171.20]:587, delay=0.46, delays=0.03/0.06/0.13/0.24, dsn=2.0.0, status=sent (250 Ok xxx )
But it seems the users are getting email delivered to them. I’ve advised them to check their spam, promotions, and social folders and to add the list address to their email safe-senders lists, but still no success. Is there any way to help this list members?
Even though gmail publishes a DMARC policy of none, it has recently started enforcing a stricter policy for mail From: the gmail.com domain. You need to apply DMARC mitigations to mail From: the gmail.com domain. There are two ways to do this.
One way is to set DMARC Mitigations -> DMARC Mitigate unconditionally to Yes (and set DMARC mitigation action appropriately)
The other way requires upgrading Postorius and Mailman core to the heads
of the GitLab branches (core=3.3.9b1, postorius=1.3.9b1). Doing this
enables a DMARC Addresses setting which can be set to ^.*@gmail\.com$
to apply DMARC mitigatations to mail From: the gmail.com domain
regardless of it's published policy.
