You ask the folks who established the block to explain it.  Since your
test worked and her mail is still blocked there must be something else
going on, e.g. it's checking the "mail from:" against the inbound IP.


(Begin "DSN 5.7.1.faq")

The following Delivery Status Notification description is lifted from
RFC1893:

"      X.7.1   Delivery not authorized, message refused
"
"         The sender is not authorized to send to the destination.
"         This can be the result of per-host or per-recipient
"         filtering.  This memo does not discuss the merits of any
"         such filtering, but provides a mechanism to report such.
"         This is useful only as a permanent error.
