When configuring a primary and secondary sendmail server, how does the
secondary mail server know it should relay anythign to the primary one?
Is it just by the mailserver examining the DNS mx records, or is there
something else in either of the sendmail configurations?

Steve,
If you are referring to relaying mail to the primary server all you have
to do is make the appropriate entry in /etc/mail/sendmail.mc by way of
the SMART_HOST feature.
define(`SMART_HOST', `smtp.your.provider')dnl
sendmail likes to have a dns server (named) active for local deliveries,
but if you do not have dns service you can specify ip addresses for your
smart host by
dnl define(`SMART_HOST', `[10.0.0.1]')dnl
