Someone in China is spamming lots of people in Japan and impersonating the 'fotoforensics.com' domain. Fortunately, I have SPF, DKIM, and DMARC enabled. SPF and DKIM are causing a 'hard fail' during delivery (never reaching the in-box), and DMARC is reporting the failures back to me.
If you run a mail server, you're hopefully already doing this. Otherwise, make sure your mail server is configured to validate SPF and DKIM, and send hard-failures to the null bucket.
