Short answer - check:

  a) syslogd
  b) /etc/syslog.conf

Long answer:

syslogd is the logger daemon, and postfix will be logging through that.

  # /etc/rc.d/syslogd restart

may fix the problem right there. Check /var/log/messages for any errors 
in syslogd startup. It may have crashed at some point or failed to start 
because of a serious syntax error in /etc/syslog.conf.

If syslogd is running ok and working for the rest of the system, then 
double check /etc/syslog.conf to see where mail facility logging is 
directed (the default is /var/log/maillog, but that could have been 
changed or the line deleted).  Check any settings in postfix for syslog 
"facility" (should be 'mail') and "priority" (if exists), match these 
against the filters in /etc/syslog.conf to make sure they are high 
enough to be logged.
