** Description changed:
+ [Impact]
+
+ Postfix backwards-compatibility notices aren't handled by logwatch, and
+ thus end up in the "Unmatched Entries" section, one per event. These
+ informational messages clutters up the logwatch reports unnecessarily.
+
+
+ [Test Case]
+
+ $ export CODENAME="focal"
+ $ lxc launch ubuntu:${CODENAME} test-logwatch
+ $ lxc exec test-logwatch -- bash
+
+ # apt-get update
+ # apt-get dist-upgrade -y
+ # apt-get install -y logwatch
+
+ # wget
https://bugs.launchpad.net/ubuntu/+source/logwatch/+bug/1583705/+attachment/5407064/+files/unmatched-entries-postfix%3Amail.log
+ # cat unmatched-entries-postfix%3Amail.log >> /var/log/mail.log
+
+ # logwatch --detail High --service all --range all --output stdout
+
+ Without the fix, there will be unmatched entries regarding backwards-
+ compatibility; with the fix there will be a simpler notice that Postfix
+ is running in backwards compatible mode.
+
+ (Note: For testing it's not really necessary to trigger the original
+ condition that produces the log entry, since for Logwatch the purpose is
+ more about making sure the entry is detected and processed
+ appropriately.)
+
+
+ [Regression Potential]
+
+ Since logwatch filters logs for errors pertinent to administrators,
+ standard things to watch out for are undesired changes in this filtering
+ behavior, such as flagging or failing to flag issues differently than
+ before, other than the specific messages being filtered with this
+ change.
+
+
+ [Fix]
+
+ [Discussion]
+
+ [Original Report]
Under the "Postfix" heading, the following lines appear as unmatched:
