Seems in your case masquerading is ok as you have a non existing FQDN
for your Sendmail host. See below the debug output of Sendmail.

That error message makes sense! Not the originally posted. Your host
rejects unresolvable domains, which is a proper setting.

No, there is no risk to be an open relay by this setting.

I would suggest you set a domain name by

define(`confDOMAIN_NAME', `satyr.bogus.jl')dnl

Make sure this bogus name is locally resolvable! Check your /etc/hosts
