Hello,

May be it's a naive question, but I don't know how to specify the SenderHeaders option in opendkim.conf.

I'm trying this:

SenderHeaders Sender,From

but emails going out of my test mailing lists seems not using Sender header in signature:

Dkim-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=patpro.net; s=patpro; t=1422439855; bh=VB7SziQTaJhyqdKLEGBbC12efU6/4GkEZv+mxEyIdo8=; h=From:Subject:Date:To:List-Id:List-Unsubscribe:List-Archive: List-Post:List-Help:List-Subscribe; b=Fjr3Z0dnkBQVMDoBo+TpCMbLsTnftn09wRPCLwcp5ZUykWyPC3lu4Lh/rxDOz6ahG JmZ83JyjrJzynh+SD//dvXEcmxhSHMzJVjCsjHm6BRJnuoiyFEfjz12weC01dbdXg6 fbqQvOt7AFXK3ncCyi2jlLqFwwB5KNjIk00Z6KoI=

There's obviously something I don't understand here because on recipient's side the signature is seen as valid even when the From: header is an email address that I don't sign.

regards,
Patrick
