Configuring the DKIM Signature

Support General Configuration
1

Hi there,

Does anyone know if there is a way of adding headers to the DKIM Signature that Axigen uses to sign outgoing email messages. An example of what current is in the signature is:

v=1;
a=rsa-sha256;
d=aelca.email;
s=2025;
c=relaxed/relaxed;
q=dns/txt;
h=from:date:to:cc:message-id:subject;

I would like to modify the h parameter to have the following so that we can comply with our internal policies on compliance:

h= From:Sender:Reply-To:Subject:Date:Message-Id:To:Cc:MIME-Version:Content-Type:Content-Transfer-Encoding:Content-ID:Content-Description:Resent-Date:Resent-From:Resent-Sender:Resent-To:Resent-Cc:Resent-Message-ID:In-Reply-To:References:List-Id:List-Help:List-Unsubscribe:List-Subscribe:List-Post:List-Owner:List-Archive

Is modification of the header parameter in the DKIM signature possible with Axigen?

Thanks for any help you can give,

Gary

Hello Gary,

At this moment changing the headers to be used when signing the message is not possible.

Till we’ll support this feature (hopefully soon) my suggestion is to check if using OpenDKIM (via milter interface) could be a possible solution for your specific use-case - via their SignHeaders configuration.

HTH,
Ioan

Thank you for getting back to me on that - look forward to it being supported in the future - I’ll have a look at the milter interface. Thanks again, Gary
