Exclude Email Address or Sub-Domain from DMARC Checks

Show all headers | View raw

I'm starting to wonder if DMARC failures due to mailing lists
forwarding my messages to them and breaking DKIM/SPF in the process
_might_ be harming my mail server's reputation*.

Can the specific email accounts which I've subscribed to mailing
lists be excluded somehow from DMARC checks or DKIM and SPF? Or a
different sub-domain pointing to the same server which I can use
in email addresses subscribed to mailing lists?

Or do I have to use a different domain entirely for those addresses
in order to bypass DMARC on the current domain? So far it looks
like this is the case, but I thought I'd check in case I missed
something.

* I know this is backwards to how it's meant to work and probably
  wrong, but there's some correlation and it would be good to
  eliminate the possibility. Plus it would clean up the DMARC
  reports I receive.
