To expand on Fritz's explanation, of forged helos, use the example of ASSP
on my mail server. ASSP is running on its own IP address, 63.150.236.20,
with the name smtp01.mathbox.net. If a remote mail server connects to ASSP
on my mail server and announces in its HELO that it is smtp01.mathbox.net,
then its HELO is forged, because the remote mail server CANNOT be me. In the
same manner, if the remote mail server announces in its HELO that it is
[63.150.236.20], then its HELO is forged, because again, it CANNOT be me.
