Author, system administrator, and developer, Peter N M Hansteen, has written a blog post about a major e-mail provider's failure to handle e-mail [blogspot.com]:

This means that after several years of mostly managing to deliver messages sent from our systems to their intended recipients in Google managed domains (at random times deciding to put mail from here in their users' Spam folders), somebody decided it was time to disregard our domains' published SPF [wikipedia.org] and DMARC [wikipedia.org] information.

Their "very low reputation of the sending domain" is is likely down to a very poor understanding of how modern mail delivery works.

More likely than not, the volume of messages sent with faked sender addresses claiming to be from our domains and a source IP address in the great elsewhere is vastly larger than the actually valid messages sent from valid users, all of which will come from the hosts listed in our published records.

The existence of spamtraps should not be a surprise either, after all we have been doing greytrapping for more than eighteen years [nxdomain.no].

I would posit that this is a mail services provider that has demonstrated that they do not, in fact, understand SMTP mail at all.

Fortunately, he was able to get the problem on their end fixed ... for now ... this time.
