first of all: Thanks a lot for creating this awesome service! I’ve been running my box for a while now and so far it works like a charm.
Currently I am not using the box as a name server for my domain, mostly because of restrictions set by my provider. I have however taken a quick look at the DNS settings, as displayed on the Custom DNS page in the admin panel, especially the DMARC settings.
It looks to me like those are set to “quarantine” for both the domain and the MX, and to “reject” for the name servers.
As a regular user of various mailing lists (and a contributer to GNU Mailman), I am worried that these defaults might make it impossible for Mail-in-a-box users to post to any mailing lists (or at least those MLs which re-use the From:-Header of the original sender, which is probably a good part of all open source mailing lists).
So my questions are these:
If I decide to use my box as a name server, is there an easy way to set the dmarc record to ‘none’, at least for the domain and the MX?
Isn’t this something that should be selectable or at least mentioned during setup, so people are aware of the ramifications for their use of mailing lists?
Again, thanks for this incredible tool!
