ok, now at least I understand what you’re trying to achieve.

I am pretty sure, though, that DKIM is not added by Mautic (it just can’t do that - if nothing else, because there is no place to add the private key).

Thus: I guess you are using sendmail delivery, right? Switch to PHP delivery and you should be fine.
Otherwise, please point me to where I am mistaken - I am eager to learn!

Hi @ekke thanks for the help, in config the mautic, i use the option “Other SMTP Server” (SwiftMailer)
swiftMailer add “DKIM-Signature”.
I will try the option “PHP Mail”
