I need to use Amazon SES services, so i must set up DKIM for all outgoing e-mails.
If my wordpress install uses smtp to send outgoing e-mail, do you guys have any ideia how i could accomplish that?
dkim-filter or opendkim? Does postfix has anything to do with emails being send from turnkey box? My guess is no, the server communicates directly with the Server.
This is the best article i could find: https://help.ubuntu.com/community/Postfix/DKIM
Any help is welcome.
