Not the originally posted. Your host > rejects unresolvable domains, which is a proper setting. 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.

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'
