[atnog] Anyone from T-Mobile Austria?

Hi Atnog/Mailop

Is anyone from t-mobile Austria reading here?

We encountered a possible misconfiguration of one of their services:

mms.t-mobile.at has no SPF record and does not sign their mail with 
DKIM. However, t-mobile.at has a DMARC record set. In a strict setup 
evaluating DMARC organizational domain, DMARC checks fail for 
mms.t-mobile.at.
As long as p=none remains, it's probably not a big issue. But should 
that ever change...

Kind regards
