The error message is clear to you? You hostname of the sendmail host
does not resolv from external. If you have control over DNS, then having
a FQDN can solve your problem.
To use a smart host for relaying you will have to activate the
preconfigured entries in /etc/mail/sendmail.mc. To be able to use SSL
you will have to create a certificate. To let Sendmail authenticate as a
client against the smart host you will have to add auth info data into
the access map file, see:
