Create DMARC TXT record for semantic-mediawiki.org

Reported here. Some e-mail providers reject e-mails coming from domains without a DMARC policy. So we probably have to cater for this bogus.

@JeroenDeDauw You will love this.

Note: Setting $wgUserEmailUseReplyTo = true; seems not to have had the desired effect, though ... see below. The WMF however does not use this either. Perhaps a tough titties situation for users of Gmail, Yahoo, AOL and consorts.

I asked for a fresh test to verify if the setting actually changed something.

Should I do something on our hosting provider?

I am afraid that we need do define this policy for the s-mw.o domain. People trying to register using Gmail, Yahoo etc. just do not get their e-mail-confirmation requests either because they are bounced or filtered away.

Unconfirmed valid requests are still happening.

So what should I do to fix this?

Can I just add a DNS entry like this: https://help.united-domains.de/faq-article/was-ist-ein-dmarc-eintrag

It seems that the main challenge is to decide which email to provide for error reporting (ruf), as this could receive huge amounts of emails. Any suggestions?

Yes, I believe so. I know that Hetzner generates such entries by default which only need to be activated at some point.

Perhaps <postmaster@...> which could be checked once in a while.

This task is not a front burner since we survived without during the past years. However I expect increased user friendliness for our mails no longer ending up in Googles spam folders (most registrations come from Gmail accounts. :( )
