I'm also get spammed 1/day/server.

The cause is #979813 whose "fix" included:

-	postrotate
-                if invoke-rc.d apache2 status > /dev/null 2>&1; then \
-                    invoke-rc.d apache2 reload > /dev/null 2>&1; \
-                fi;
+    postrotate
+	if pgrep -f ^/usr/sbin/apache2 > /dev/null; then
+	    invoke-rc.d apache2 reload
+	fi

which dropped redirection in the reload line.

Changing querying status to pgrep is also bogus: it will detect any apache2
process rather than just ours.  But this is not the issue at hand.

To stop the mails from logrotate, could you please change back:
-           invoke-rc.d apache2 reload
+           invoke-rc.d apache2 reload > /dev/null 2>&1

otherwise, people running Bullseye will be mightily unhappy.

I also wonder why such a cleanup was done late during hard freeze.
