Sorry, that's not correct what you say about SMART_HOST.

define(`SMART_HOST', `host.domain.tld')dnl

is the right way to tell Sendmail to relay (the relay mailer is used 
implicitly) all outbound mail to that specified host.

But it is important to pay attention for the order of statements in the 
sendmail.mc configuration files, as one of the first chapters of the 
cf/README explains.
