Try the below. Note, if build as below, it will not replace your system
Postfix, all the installation paths (including the queue directory)
will be under /opt/postfix, you can then update /opt/postfix/etc/master.cf
to spin up an SMTP listener on just a non-conflicting port (comment out
port 25) and run both the system Postfix for real mail, and this one for
testing:

# postfix start
Don't confuse the two Postfix installations, make sure your
PATH is set correctly to list /opt/postfix/sbin first if
and only if managing the debug install in /opt/postfix.
