Hello All,

I first wanted to know how can an envelope sender who says they are from our
domain send a message to us, when we thought ( operative word ) we were
blocking that from happening?

Additionally we are using SPF and in this case SPF should have failed ( says
it did: does not designate 90.37.16.113 as permitted sender ) ,

 it shows in the log file the following:
