Actually, it says something like:
Jan 3 hh:mm:ss hostname postfix/qmgr[pid]: QUEUEID: from=<sender>, size=x,
nrcpt=y (queue active)

Normally, some delivery process will report "status=delivered",
status=bounced", or "status=deferred".
If that information is missing, then either your delivery process
is failing (and you are missing its warning/fatal/panic logfile
message), or your logging is busted.
To fix an invisible failing delivery process, you need to find out
where its warning/fatal/panic log records are written, read what
the records say, and correct that problem.
To fix busted logging:
1 - Disable SeLinux or AppArmor or whatever and see if that makes
a differerence.
2 - system-effing-d-based versions of Linux lose logs under high load.
3 - Recent versions of MacOS have an unusable logging system.
To fix [1], update your SeLinux or AppArmor or whatever policies.
To fix [2] or [3], Postfix 3.4 comes with its own postlogd logging daemon.
