That's going to be deeply flawed on macOS. Ubuntu (as a Debian 
downstream) does major violence to the Postfix package and a tutorial 
won't map directly to macOS.

Sent by what means?
On what version of macOS?

It's hard to say where you'll find logs, since you haven't mentioned 
your macOS version.

In an older version (10.x, basically,) you will get messages in 
/var/log/mail.log unless you've done something odd to /etc/syslog.conf 
and/or /etc/ASL.conf. The logging subsystem mostly worked like classical 
Unix/Linux syslog.

In modern macOS, Apple wrecked logging worse than Linux did with systemd 
and its rate-limiting. Wietse addressed both platforms' problematic 
logging by creating a logging subsystem just for Postfix called 
postlogd. Use that. Like all of Postfix it is well-documented.

The most likely root cause if you are using the standard command line 
tools is that you're using the Apple tools that expect to talk to the 
standard system Postfix, with sendmail under /usr, the spool in /var, 
and config in /etc/postfix. To fix that, you will need to put 
/opt/local/bin and /opt/local/sbin ahead of the system directories in 
your PATH environment variable.
