What to fill in if you want to receive reports to feedback.mycustomer@mailingdomain.com?

  • Domain: tag d of DKIM signature → mailingdomain.net
  • Selector: tag s of DKIM signature → k1 or * for all selectors
  • Header name: client identification header → X-CampaignId
  • : regular expression with one group matching the client id; in this case a string before dot in the header value → ([\w^\.]+)\.
  • Report consumer: report delivery address → feedback.mycustomer@mailingdomain.com

The result will look like this:

Domain:mailingdomain.net
Selector:*
Header name:X-CampaignId
:([\w^\.]+)\.
Report consumer:feedback.mycustomer@mailingdomain.com
