DKIM fixed domain in signature

[Sebastian Salmhofer]

Hi,

I am trying to configure DKIM signing for all domains on the gateway but with the same d= tag in the signature.
So there is one DKIM Key and DNS record, say on domain-x.com. The gateways are also called mail01.domain-x.com and mail02.domain-x.com.
Now I want PMG to DKIM sign all outbound mail, e.g. for the domains abc.com, xyc.com and etc.com, but use d=domain-x.com in the signature for all of them.

I implemented this solution before with other mail gateways and it works great and has the benefit of only needing one DNS record for all domains.

Is there a way to configure this on PMG? GUI or manual is fine, too.

Thanks
Sebastian

Currently this is not possible with the DKIM signing implementation in PMG (you can of course install some 3rd party tool (dkim milter, dmarc milter....) and let that do the signing, but that means manually adapting the config).

If you want - please describe the desired behavior (and link to this thread) at:
