That _may_ be caused by receiving mailservers refusing to accept obviously
faked mail becuase:
a) the from: domain does not resolve (hence is probably spam)
b) or the from: domain does resolve, but it does not resolve to your IP
address, hence your mailserver is probably relaying 3rd party mail (POPAuth
excepted) , hence is probably being used by a spammer.
