The host itself is running SMTP, but I'm not sure whether sendmail will try the domain part of the address as an MX - maybe there's an option for that, buried in the murky depths of the cf file. The DNS lookup is failing because sendmail, I expect, is sending a query only for MX. Mark To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
