Is PHP's mail(..) function supposed to sign with DKIM?

    I have enabled DKIM for one of my domains, but e-mails sent with PHP's mail(..) function are not signed. There is no DKIM header present. Is this by design?

    - Thanks in advance

    I think this is the case with amavis; I don't remember/know about rspamd right off. A workaround is to use SMTP, of course. (Some folks would consider that a feature - you can't send signed email just because you live on the same server as some mail domain, you actually have to use a username and password to have signed email.)

    Thanks, @Jesse Norell - that's completely fine. I just wanted to make sure this was not caused by misconfiguration or a bug. Thank you :)
