our setup does not allow us to change SPF records. Which is fine - but we would like to utilize the "On Behalf of" or "Via" by using a "Sender" mail header. This forum post from 2015 explains that CiviCRM does not have the "Sender" mail header - but is there any work on this? Both MailChimp and SalsaLabs have this feature.

  • If there's a hook that allows changing the mail headers, this would only be a few lines of code to implement as an extension. Implementing a hook itself is only a few lines of code, so someone could conceivably write the hook, then the extension. Feb 15, 2018 at 20:20
