Yes. The purpose of this script is to group logfile records for
the same mail delivery transaction.
This will help you to find out what happened with the messages that
are the subject of your investigation.
If the remote SMTP server accepted email, then Postfix will log
"status=sent" and the remote SMTP server response will contain an
identifier that the server's administrators can use in further
investigations.
Examples:
Apr 6 05:09:40 spike postfix/smtp[14214]: 48wl9F4n0dzJrNs:
to=<recipi...@example.com>,
relay=gmail-smtp-in.l.google.com[172.217.197.26]:25, delay=9.3,
delays=6.9/0.018/1.1/1.3, dsn=2.0.0, status=sent (250 2.0.0 OK 1586164180

Apr 6 09:10:04 spike postfix/smtp[17719]: 48wrVh2cdHzJrNt:
to=<other@other.example>, relay=mail.cloud9.net[2604:8d00:0:1::7]:25,
delay=0.24, delays=0.13/0.026/0.068/0.016, dsn=2.0.0, status=sent (250 2.0.0
Ok: queued as 8DED4336382)
If the remote SMTP server rejected email, then Postfix will log
"status=bounced" or "status=deferred" and the remote SMTP server
response will say why.
