To stop this you need to have "In general, restrict relay mail except as
indicated below: " dotted, and only the 1st box "Allow relay from these
IP addresses:" to be checked. Then list IP's allowed to relay.
Then in the second section "No domain except those listed below:" should
be dotted (by default) and neither of the boxes checked.
This will make it relay strictly by IP only. That is the only way to
really secure Post.Office.
