That is really meant to be a server name, not a number:
/usr/src/usr.sbin/smtpd/parse.y:645
opt_relay : BACKUP STRING {
Hi,
I meant that you specify a value as a *number* like this:
"relay backup 20"
and then, the backup server would relay to all MXs where the value is
lower than 20. However, since you didn't specify a value (which, as I
read it, should be a number), all mail gets relayed via the default
server
