New bulk email requirements for gmail?

Hello! :wave:

I am an admin of the QIIME 2 Forum, and we recently received this email regarding updated requirements for bulk email senders:

I checked our forum digest email frequency, and we don’t meet the daily email frequency threshold that these requirements are for - but I was curious on Discourse’s email standards as a whole. Does Discourse use DKIM? And more generally, do you have to adhere to these requirements:

Thanks for any insight you can provide!

Hi Liz,
maybe a small misunderstanding: Discourse acts as a mail client in this case, similar to a local mail application. Security settings for mail transport like DMARC, DKIM and SPF are provided by the SMTP server handling incoming mail from a (self-hosted) Discourse instance. These technologies are required by all major mail providers to avoid spam and increase secure deliverability.

In my case (self hosted Discourse at the mail is sent to as the mail provider. The DKIM record comes from the DNS domain settings (TXT record) and is checked by the SMTP provider. As another measure of spam protection, SPF (sender policy framework) defines the mail servers which are allowed to handle incoming mail from my domain

In your case I would guess that you need proper settings for the incoming mail at
