Hello,

I was testing my mailer service and have 10/10 on www.mail-tester.com and also good reputation on new www.mailgenius.com

But i have a warning that i need to add a "List-Unsubscribe header" implemented on 2019 as a security measure.
I think it must be done on EXIM configuration file or Roundcube. But i dont know exactly which file to edit and what text to add.

Just an old reference on: https://saeedrahhal.wordpress.com/tag/exim/

Anyone have manage to add this header correctly?

Regards,
Javier

Exim has nothing to do with "List-Unsubscribe"
Roundcube has nothing to do with "List-Unsubscribe"

"List-Unsubscribe" should be set by mailing-list software (that act as 'mail client')
Since Roiundcube is not mailing-list software, it should not be set by Roundcube.
