Re: hi myhdl

Often times, the account in question wasn't hacked, but bots merely faked the from address along with other mail headers to cover their tracks.  In the original SMTP specs, there's nothing to prevent From forgery, but in the recent years, DMARC was developed specifically to allow domain owners to lock down their domains to prevent such third party forgeries.

DMARC has raised some controversy, because for locked-down domains, it also prevents naive mailing lists from relaying messages --- but any real list server software today can interoperate with DMARC now.

It looks like this domain "djnewmoney.com" did not publish any DMARC DNS records
https://dmarcian.com/record-tools/djnewmoney.com

But if it did (and with the underlying SPF and DKIM records, too), then all other email servers could easily spot and reject these forgeries.

Examples of strict DMARC records:
https://dmarcian.com/record-tools/google.com
https://dmarcian.com/record-tools/yahoo.com
https://dmarcian.com/record-tools/citibank.com
https://dmarcian.com/record-tools/paypal.com
And my own domains:
https://dmarcian.com/record-tools/ad5ey.net

Summary: Any domain is at risk for these From forgeries, and I wish more domain owners would opt into DMARC to stop such schemes.
