Look at the headers and work out what really happened.

Forging email addresses is trivial.  It is the work of a few seconds
to send an email with somebody else's email address.  You can mitigate
somewhat by using SPF and DKIM, but it does require that everybody
checks your SPF and DKIM records - not everybody does.

                 Please keep list traffic on the list.
