I used to get tons (100-300 a day) of "backscatter" emails - emails that
were supposedly sent by me but bounced back because the recipient didn't
really exist. I use a web hosting company for my website and email so I
had them enable SPF (Sender Policy Framework) on my domain and all that
stopped within a few days. I'm not an expert on it but the way I
understand it, any email received by a compliant system is supposed to
check if SPF is enabled and if so, verify the email is from a legitimate
source.
Here are more details:
