EmailDiscussions.com - View Single Post - Gmail silently discards forwarded email for sender domains with SPF record "-all"

Peter, the SPF records of the sender From header domain (nyheder.bilka.dk) is basically:

Code:

v=spf1 include:emarsys.net include:emsmtp.com ~all

So SPF specifies softfail. The DMARC record is:

Code:

v=DMARC1; p=reject; adkim=s; aspf=r; rf=afrf; pct=100;

So DMARC requests rejection (which may mean silently discarding) such messages if both SPF and DKIM fail. We can't tell if the message was properly forwarded with SRS (allowing SPF to pass) or if DKIM passed when received at Gmail.

But this is a message from a bulk marketing company, and the Fastmail global Bayes score is already 50%. Gmail may be rating that message much worse based on user reports or other criteria and discarding the message as too spammy. Was the From address or From domain (nyheder.bilka.dk) whitelisted in the Gmail account? I don't think you can expect 100% delivery of messages from a bulk sender with a significant spam score (at least from SpamAssassin) which are then forwarded. This SpamAssassin tag also is of concern: MIME_HTML_ONLY
