Heho,
I signed up for the sender support (sendersupport.olc.... ) of Microsoft and
activated forwarding of messages flagged by users as spam. Today I saw an email
sent by microsoft to postmaster@ with a from of one of my domains rejected
based on the domains DMARC policy by my mailer.
Based on the data in my rspam log and the sendersupport site showing ~1 mail
having been marked as spam by a user, I _suspect_ that this is the forward
feature; However, this feature seems to break DKIM signatures and re-signs with
hotmail.com, leading to the DMARC policy reject triggering, as neither SPF nor
DKIM match;
Is there any good way to get into contact with them about this (as this is not
really me having issues sending to them, but them to me ;-))/is anyone from MS
reading on this list?
With best regards,
Tobias
