No, this is incorrect, at least on bookworm (it gives just a few logs):

Sep 08 01:50:46 joooj systemd[1]: Starting postfix.service - Postfix Mail Transport Agent...
Sep 08 01:50:46 joooj systemd[1]: Finished postfix.service - Postfix Mail Transport Agent.

Using a pattern

  journalctl -u postfix\*

gives any log related to postfix, but this is terribly slow
(more than 3 minutes on my server!) and limited to postfix
(nothing about spamassassin, for instance).
