According to the announcement by Google1 and Yahoo2, they require all bulk emails to include:

  1. Full authentication, including SPF, DKIM, and DMARC.
  2. A one-click unsubscribe.
  3. Sending emails only to users who need them.

The #1 was completed last year; the #3 has always been Quail's practice, never sending any emails without the user's active consent. The #2 was completed in this week's update.

The so-called "one-click unsubscribe" mentioned in the #2 is a link that appears next to the email recipient:

Clicking this link will directly unsubscribe the mail list, without the need to navigate to a webpage.

To implement it should follows RFC80583 by adding to the email headers:

List-Unsubscribe: <URL>
List-Unsubscribe-Post: List-Unsubscribe=One-Click

Additionally, to more strictly adhere to the #3, email imports have been temporarily disabled. The plan is to introduce a 2-step opt-in process for email owners to confirm their subscription.
