I don't think this message is from his HOST. Its from the Smart host
he is directing his sendmail MTA to at something like:
[smtp/mail].verizon.net.
It is unable to lookup his bogus fqdn. And unless he masquerades as
an domain that machine knows, it will not let him relay. Hence his
setting Masquerade_as = verizon.net. Seems correct to me.

Now this puzzles me. It seems to indicate what I said above is wrong.
Maybe it is. Jorge, is that in your sendmail.cf? Can you post the
result of:
`grep -A1 'who I masquerade' /etc/mail/sendmail.cf'
