Ubuntu + Postfix: Mail Log Missing [duplicate]
Apparently, this was a permission issue for some strange reason. I tried the answers from this post below that sorted the issue.
Ubuntu 14.04 System Logging
sudo chown syslog:adm /var/log
sudo chmod 0775 /var/log
sudo service rsyslog restart
sudo service postfix restart
Not sure why the /var/log was locked to root when I've always been on Ubuntu 14.04 and not upgraded fom 12 where root would be default.
