qmail equivalent of Sendmail's SMART_HOST?

[Martin Gignac]

Hi,

If I have a mail server behind a firewall, I know I can use the SMART_HOST
feature in Sendmail to send all non-local outgoing mail to a predetermined
relay somewhere beyond the firewall who will take care of sending mail out
onto the Internet.

Now in qmail, how do I achieve the same behaviour? Do I need to use the
'smtproute' file, or is there a more 'standard' way of doing it?

Thanks,
-Martin
