Hi,
a potential hosting provider is requiring a specific form of one-click unsubscription link/button for all sent newsletters, as per https://www.ietf.org/rfc/rfc8058.txt and as part of the CSA (certified senders alliance) standard, which in turn whitelists newsletters for some larger email providers.
So my question is: can this be done with phpList?
This is the example they give:
List-Unsubscribe: mailto:listrequest@example.com?subject=unsubscribe,
https://example.com/unsubscribe.html?opaque=123456789
List-Unsubscribe-Post: List-Unsubscribe=One-Click
And this would be the post request generated:
POST /unsubscribe.html?opaque=123456789 HTTP/1.1
Host: example.com
Content-Type: application/x-www-form-urlencoded
Content-Length: 26
List-Unsubscribe=One-Click
Can phpList work with such a post request variable and directly unsubscribe a user without him having to click another button?
Thanks for your help!
