From what Jorge quoted as communication is the SMTP dialog with his
Sendmail, not the MTA of verizon.net. Please review the whole process
Jorge posted. Even if you use a smart host with Sendmail, the local
Sendmail acts as an intermediary, it queues the mail to send out until
it got processed with the smart host.

I would like to see what Jorge has in his /etc/hosts file, for localhost
and satyr.bogus.jl.

That the FQDN couldn't be looked up irritated me too. Whether verizon
requires a resolvable FQDN for all who send mail through their customers
MTA (acting as smart host) should be pointed out by the support of
verizon.
