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). -- Vincent Lefèvre <[email protected]> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / Pascaline project (LIP, ENS-Lyon)
